They left the group instead, a perfectly valid option for when the tank is not conforming to the desires of the group if they are the leader.
I could argue that the healer sets the pace just as much as the tank.
And? Are they immune to criticism because it makes sense for tanks to lead dungeons? What are you even saying? If they’re going slow and everyone else in the group wants to go faster, that’s an issue and there’s nothing wrong with saying so.
I’m saying shut up and come with me if you want to make it through the dungeon alive. 
The point is, no tank cares if you want to go faster. Being unwilling to compromise isn’t great, but I’ll pull things how I choose based on the tank’s kit or the mob type.
If you wanna go faster than I’m going, find yourself another tank.
Bro it’s a level 30 dungeon in Wrath pre-patch where our characters are uber buffed relative to the content, which is also more nerfed than ever, I guarantee they don’t actually need a tank.
Ignoring what everyone else in your group wants because you’re the tank and you need to be the boss is toxic af.
Then why pick one up? Why not just roll 4 dps and a healer since a tank isn’t needed?
If the tank doesnt want to go that fast, for whatever reason, then nobody has the right to demand he go faster. You can either kick him and tank stuff yourself, replace him with a new tank, or finish that dungeon at the current speed and find a new one after. You have no right how to tell someone else to play, until you pay their monthly sub.
You easily could. People were even doing this leveling in TBC.
lmao why not??? What?
You honestly think it makes sense to do this without even suggesting that the tank pick up the pace? What are you people?
It’s a group activity. Play to the group or GTFO.
And I can definitely suggest to a tank to go faster because everyone in the group wants to go faster without paying their monthly sub. That’s an absolutely ridiculous notion.
…then why aren’t they? It would make much more sense to pick up another dps if a tank truly isn’t needed.
Many groups are, I’m sure. Some prefer the “holy trinity” but a lot of people have realized it’s unnecessary in low level content, especially at this point.
If a tank isnt comfortable with going faster and you ask him to and he says no, at that point you literally only have 3 options. Kick him, replace him, or shut up and finish the dungeon with him. You cant play his character for him, nor can you force him to go faster.
I’ve never seen it. Not even once. I play my mage a lot.
Ignoring what the tank wants because of what your or the group wants is the same thing. Yeah it’s meme leveling dungeon NBD, but the principle stands. You need him, and he doesn’t need you.
Instead of kicking and replacing you would have to leave if you’re not lead, which is what they did.
You don’t say!
1 healer, 4 casters easily melts SM dungeons. Nobody cares that you haven’t seen it. It’s a thing.
Oh, they can solo the dungeon? Not at that level. The tank needs a group, too.
Primadonna tanks don’t get to waste everyone else’s time because of their bizarre need to be in control. Especially in extremely easy dungeons where they are literally not needed. Just replace them with a dps if they’re going control freak mode, it’ll be fine, I promise.
Healers are also more scarce than tanks while leveling. But nobody’s saying you have to worship the healers’ feet in dungeons.
I don’t think a tank at that level can solo SM. He can immediately find a new dungeon group.
Hyper focusing on the level of the dungeon is missing the point tho
Yeah, he can magically come up with a healer when nobody levels in heal spec. Mhm.
Yeah you’re hyper focused on this narrow level range rather than actually understanding the problem the OP brought up. His example was SM, but his argument spans the whole game.
Nobody levels in heal spec. How is that indicating that I am focused on a narrow level range?
You don’t need a tank for the first 40 levels. Very narrow level range.
Because this stuff happens at level cap. Where there are healers, more than tanks even.
Its better to build the tendencies now than later. At later levels you wont just kick the tank unless you have one lined up. You dont stay 30 forever.
