it's the same problem as when you vote for abandon, people reject it and you see people leaving because they don't accept a group decision. SE must remove the "leave" button completely. if you join, you stay and that's it. and if you go offline or AFK just because you don't accept staying in that party, people vote for you to be dismiss and you cannot register for a new dungeon or RAID for 3 days.

people will stop being pain in the ass by joining for just leaving and not accepting a group decision to not abandon.

SE is too much cool with those people and it's worst every day.
