Why you can't kick people in combat?

[Jeeqbit]

Someone could wall themselves and refuse rezzes the whole fight and still "get the clear" because some people in the party decided to enable it.
That doesn't make it not a problem.

It's not a problem. You know why? Because you were able to clear.

You take issue with someone being carried, but the problem with that is they could just unsync most content and get "carried" that way anyway. So what does it matter?

It's only a problem if it's preventing you from clearing the fight. It's only preventing you clearing the fight... if everyone wipes. If everyone doesn't wipe, then obviously the fight isn't difficult enough to require this "lazy" tank.
