IMO there's just kinda "Norm" here that Tank is the only one to pull without any communication
So your doing is opposing that norm whether you know it or not but you already opposed it
Then people will think "You're the bully" and no one want to play with bullies
So the others decide to booted 1 bully for 3 people's sake

What I want to tell you is people here aren't that sensitive but we kinda strictly running with that norm
And when it's norm, You then need to know it to join the social(Novice Channel can tell you some)
When everybody go with the norm there's no need for communication (for introverted as me, I don't want to speak much just wanna play the game)
If you wanna do something different from the norm please tell before you've done (that's the norm here too)

With respect
