I’ve seen numerous posts recently about how someone ran a low level dungeon and the tank left, but the group carried on using their CC and other tricks to get through the dungeon, all of this leading to the conclusion that we do not need tanks.
Maybe we don’t really need a tank in the very low level dungeons, but I would argue that this is primarily due to the effects of Heirloom gear and playing with people who are not new to the game. It’s something entirely different when you get into a group of people who are truly new to the game with no heirlooms and often little concept of how a dungeon works.
I’ve healed a Ret pally in good PvP gear with Righteous Fury thrown on as “tank” through heroics. It can be done.
I’ve been in these situations, and yes, it is a lot of fun.
Can we raid without tanks? Considering the amount of damage most raid bosses put out, I highly doubt it. Sometimes it is hard to keep the tanks alive as it is.
There’s nothing saying you can’t get a group together that lacks a tank and run 5 mans, but please don’t impose that on me in random LFD pugs. It’s sometimes hard enough coping with the variety of characters out there as it is. When I was actually trying to level up a tank through the LFD, I got rogues who wanted to evasion tank and shamans who wanted to tank. That’s great, but do it on your own time with your own group, not in my LFD pug (at least not without some kind of agreement with the rest of the group).
