I only use one round of consumables for BWL, MC, and ZG each. Everything is done in an hour or less. I don’t use Zanza for ZG, and Titans only for BWL (and I might save it next double-raid to see if there’s any risk of me dying).
I guess for slower raids they can’t clear fast enough to for the gold to pay it off, but I usually come out of ZG wealthier.
I don’t do consumables for ZG at all. We treat that raid like UBRS. It isn’t on the guild schedule and no EP is earned. Group loot rules. If I add in ZG money, then I probably break even.
Which consumables are you using? That makes a difference too. If you aren’t using firewater or juju for MC then that alone drops the overall cost.
Zanza, Mongoose, Greater Defense, Elixir of Fortitude, Brute Force, Dense Sharpening Stones, +12 stam food, Gordok Grog.
Ah. I see. The Brute Force instead of firewater and no juju. That lowers the number of things you need to pop. Not downplaying the expense of your list either. Just different. I assume you tank too with the Greater Defense, Fort, and Brute on there.
Do you farm the mats or buy them? Genuinely just trying to learn at this point 
I buy the potions, though I farm some. While DPS, I farmed Elemental Sharpening Stones for 1-2 hours on a day off, and that would set me for a month of raiding. Now, I might run an odd dungeon for 20-40g.
good thing we have 40 people who pay attention when the tank calls out “parry, parry, dodge” 2 seconds after pulling the boss
Honestly flanking is cool and all but mc and bwl 8s super easy content I’dsave it for aq honestly. Cuz the content is super easy to do without flanking atm
Your min/max guild can completely buff itself in 15 min? That’s seriously impressive.
My guild is totally capable of doing bwl without the buffs, yet starts invites to the DM tribute buffs about an hour to 1.5hrs before actual raid start time. After that long and drawn out process, we grab a songflower, hit org (and now usually hakkar buff too) and then hearth to kargath. We spend a lot of time gathering buffs that might last us until firemaw.
if i lost buffs before firemaw every week I surely wouldn’t get them. at the same time, i cant imagine a guild whose average member loses buffs before firemaw every week would be in a position to require or even incentivize grabbing world buffs.
If you are out aggroing the tank, you are doing it wrong. It may be a tank’s fault he is not gaining much threat, but it is entirely your fault if you draw more threat than him or her.

Thanks for the resume, we’ll keep it on file.
PVP servers say hello. Half the time I have to fight through Horde just to enter the raid instance. World buffs very easily become a waste of time. The good elixirs are also getting more expensive by the day. If your group isn’t struggling to clear the content, why bother?
I have to watch my threat as it is. If I were world buffed and flasked out the wazoo, I would spend more time feinting and vanishing then I would DPSing.
That’s the thing, is it really worth the time and expense to buff/flask/etc if all it would take would be for DPS to watch their own aggro?
Parse stroking is as toxic as damage meter posting after each fight.
In my opinion, no. The only exception would be if your group is under geared and struggling. When I first started raiding with my guild, I was under geared and not even close to pulling threat from the tanks. Now that I’m much more geared, almost every fight I’m close to pulling threat if I’m not careful. As soon as I start back stabbing I shoot up the threat meter. 
Damage meter posting is prohibited in my guild.
My 2c:
World buffs and most consumables aren’t needed for the current content. Collecting all the wbuffs and farming for the consumables costs more time than it saves during the raid.
Does that mean wbuffing and flasking should be banned in your guild?
In my opinion, no.
While collecting world buffs and consumables is not needed in current content, it is very likely it will be necessary for an average guild to down Ch’tun. Current content is very easy. It leads to good and devoted players being bored. The way they entertain themselves is by chasing parses and cleartimes.
If the majority of your guild doesn’t parse high, due to either skill or lack of wbuffs/consumes, a skillful buffed player can’t parse high despite his effort. Thus, such a player is likely to leave your guild and join one where wbuffs and consumes are widely used.
If parse chasing players leave your guild now, you will not suffer major consequences… yet. But it is likely that your guild will have trouble clearing AQ40 in the next phase… and very likely your guild won’t be able to clear Naxx. Because your most devoted players have left long ago. Now you must flask… use all consumes… get all world buffs… and your DPS optimization matter. You need a full roster. A few people say, this is not fun, and gquit. And now your guild is dead.
Tryharding on easy content is training for hard content. Is Naxx hard? Compared to mythic raids in retail, probably not. But how many Classic players are mythic raiders? I am not. Are you? Is the majority of your guild? If not, Naxx will most likely be hard for your guild. If you want to clear it, you should practice the pre-raid routine and make sure you have a devoted roster while you can still recruit new players.
says the mage who spams frost bolt and nothing else for 95% of all raids. Also the class that can solo level dungeon aoe grind with minimal effort while also making absurd amounts of gold.
I am NOT a “tryhard” raider in Classic. Until the end of Legion you could say I was “moderately tryhard”. I got cutting edges and had my share of 400-800 attempt bosses.
Are Naxx and AQ40 hard? From what I’ve read about the bosses and the numbers available to me, I would say yes. They aren’t Mythic content, but they aren’t heroic content either - they are hard in the sense that awareness from every member in the raid matters and mechanics that aren’t respected can quickly lead to a wipe. You WILL down Naxxramas if your guildmates actually learn how to do it properly, but there really isn’t any cheesing available if your guild isn’t capable of doing that. By comparison, decent guilds will obliterate most, if not all heroic bosses within a few hours after a raid’s release simply because heroic raids are so undertuned that a good output of healing and DPS mean that any mistakes can usually be glossed over. There are fewer opportunities for mistakes on C’thun when compared to retail heroic raids, but when you make a mistake in C’thun you just die, usually taking a few people with you.
AQ40 and Naxx are going to be super easy for very good players, but are you a very good player? Can you at least clear heroic content on retail reliably and easily, which I would say is the line that separates people who actually like raiding from people mildly interested in WoW but who never actually took the time to learn the game? People whose answers to the second question are “no” will be in over their heads.
By the way, nothing that I just said justifies ever using flasks for Blackwing Lair and Molten Core. Doing that is completely useless and a massive waste of time.
