I agree the vote kick option definitely needs a rework in their rules.

However, there are some perfectly good examples of why 'different playstyles' is a legitimate reason to kick someone. If I was in a group with you and a melee and you kept knocking back mobs and slowing us down at every pull, I would probably kick you aswell.

Another example would be three players wanting to speed run and one player running to every room and pulling the mobs. They want a full clear, we don't - and they're slowing three other people down in the process. That's a different playstyle.

I mean, if knock back is the only thing getting you kicked, is it really that hard not to use it? Also skills are situational. Tanks have stun but it doesn't mean they should be stunning every mob they see.
