A vote kick is a majority call, meaning more people then not say to kick, this means at least 2 people are being mean to 1 person. Now this is bad for the 1 person if in fact they are doing nothing wrong, however, with no vote kick system all it takes is a single person, 1, to make 3 people unhappy, and most of the time its the tank with instant ques whos being the meanie.

I just had a tank go afk because we had a lvl 50 trying to run the dungeon to unlock another part of the game, i believe he said AB. The tank refused to play for no meaningful reason and was mean to the other 3 group members. So as you can see the system already has in place a way to abuse it. Players are asking for a way to remove those who abuse the current system and by making it vote kick it reduces the chances of someone getting kicked for no reason.
