not because of the game, just because one person took what was supposed to be a chill co-op experience and intentionally made it the worst possible version. please do not do this to others. even if you do pull like that as a tank, if the healer clearly can't keep up, slow down. don't be that guy.
This has been every dungeon I've run in TWW. It's like every tank is doing some kind of mythic timed run strats regardless of what I want/need as a healer. I'm just running as fast as I can the whole time, using Renew and instant cast spells, and basically never touching Heal or Flash Heal.
I don't queue as tank any more because my style is to pull cautiously and make sure the healer isn't out of range; that's when DPS starts pulling anyway then I get the verbal abuse (and sometimes vote-kicked).
the unfortunate thing is the incentives are all on the tanks side - their queues are instant, if people leave because of them, those people get timers, but they don't and people won't report the tank because it may mean waiting around for a while again
