"You pull, you tank" is a bad mentality

[Saraide]

So it's bad if 3 want to go fast, but okay if 1 wants to go slow...

Okay, let's make it a vote. 3 want to w2w, 1 doesn't. Majority rules in favour of w2w. Tank now has a choice of staying and realising they have the easiest role to play, leave and take the penalty, or risk getting suspended/banned because they refuse to work with the Party (demanding to be kicked, going afk, "disconnecting," etc).

(bolded by me)
This is really the part that confuses me the most here. Nothing changes for the tank. You still just hit aoe and mitigation. Doesnt matter if it's 3 enemies or 300. There cant even be a difference in playstyle. It's just sandbagging.
