Correct. For Vote to Kick, it is majority rules, though character history on using the Vote to Kick system and if certain individuals queued together are taken into account.
Additionally, yes, the only reporting option available would be to report inappropriate language/subject matter, or cheating/exploitation, etc…
How they may be playing their class or fulfilling their role is not something we’d generally be able to intervene on. The Vote to Kick system was implemented to allow the group to determine when someone doesn’t exactly fit within the current group.
I believe any discussion on how you’d like to see the system changed would be better in the thread I originally moved to the Dungeon, Raids & Scenarios forum.
