Many of these might seem obvious but from the runs i’ve done they aren’t known by all, This tips wont always be applicable once you are doing end game dungeons and raids. these are for the dungeons you are running while leveling.
Tanks:
Stack stamina and strength, you don’t need hundreds of spirit, your health isn’t regenerating in combat. agility isn’t good for leveling warriors because when u dodge you don’t get rage.
Bear druids can’t block or parry so agility helps with damage mitigation but if you are having a hard time building rage you can replace some agility with strength, allowing for harder base hits and allowing you to be hit more often building rage quicker
unorthodox tanks like rogue or hunter who tanks, they need as much agility as possible.
If the healer is getting aggro your most likely doing something wrong, either you health is slow and the healer is trying to heal you as you pull which if u waited literally 3 seconds that wouldn’t have happened, or your not tab targeting or doing enough multi target aggro so when the healer drops a a big heal they pull.
the only other option is the healer is just spamming heals and intentionally trying to go oom to get everyone killed, which almost never happens.
if dps keeps dropping aoe abilities right when you pull messing up all the aggro just kick them and move on. they either are missing some brain cells or just don’t care, so they need to go, you can replace them or move on, most dungeons can be done by 4 people or even 3.
Get a ranged weapon, not every pull needs to start as a charge, many pulls work best with a range attack and then some los to group the mobs together around a corner.
Healer:
stack spirit and int, don’t ignore either stat. it takes 5 seconds from your last cast for your mana to start to regen. don’t spam heals it wont let your mana regen, it might take longer to do a big heal but doing 1 big heal is far better than spamming the small one. your not going to be kicked for letting someone go down to 50% health, half the time their health needs to be that low so you don’t waste mana on the heal.
If you have to drink every pull you or your group is doing something wrong, as someone who plays a healer in classic i almost never have to drink, many dungeons i never run out of mana in.
not everyone needs to be at 100% health at all times. many times a hot on a dps or yourself is all you need to get your/there health back up to full by the time all the mobs are dead.
do test heals when someone has lost health to see how much your heals heal them. sometimes 2 big heals on a mage will give them full health form 1% but for the tank it might take 6, learn how much your heals heal on average and how much health your players have.
You will be treated like an npc and the group will most likely only say something to you if your doing something wrong, you wont be getting complemented for a flawless and quick run. healing is a thankless job, but you have a good chance of getting the loot you want, unless you keep getting mages in warlocks in every group.
DPS:
Unless you are a warlock stop stacking stamina, you shouldn’t have more health than the average tank, your wasting your other stats like intellect agility and strength
Stop throwing out as much dps as possible the second the tanks pull, unless you have dots don’t be throwing out abilities for a few seconds to allow the tank to get aggro, also when you not aggro hogging you can see which mob the tank is focusing on, which should be the mob you focus on.
AOE is not always the answer, unless most the mobs are around half health or less you shouldn’t be dropping aoe. just because you can kite the mobs around until you run out mana doesn’t mean you should, the tank can’t hold aggro because he/she isn’t being attacked and when you finally mess up and die everyone but the tank is going to have aggro causing group wipes or long wait times between pulls because people need rezed healed and replenished mana. you might think your running the dungeon faster but in reality you taking twice as long.
Use your slows, roots, and stuns, most classes have some sort of cc that can stop or slow a mob running away with low health about to pull another group, don’t assume the guy next to you is going to be the one to do it, if the mob is running slow root or stun it.
Learn a rotation. and when to change it. mages warlocks and shamans have long casting times for their main damage abilities, sometimes auto attacks from a wand or staff is better, if you have to cast shadow bolt 3 times and every time right before it goes off the target dies you just spent 10 seconds doing nothing.
warlocks specifically, if a target has less than 50% health unless its a boss it generally isn’t worth dropping all your dots before you do anything, they generally die before you get a few hundred damage out. 1 shadow bolt and 2 wand attacks might be all you have time for.
That’s all for now, these were just off the top of my head, the things i’ve seen that bug me. if you have anymore good tips let me know and ill add them
