I don't really know how common is the essue or if this is something that just happened to me. Last night I was doing a Brayflox HM on the DF. Everything was going great, everyone knew what have to be done until the second boss. After we beat it one of the dps said that it had to go. The other dps the tank and me ( the healer) just continue normally waiting for him to drop so we could get another dps. Then he said to vote kick him. The dps and me was like "why?, just leave if you have to go". Then he said that if we didn't wanted to 3 man the rest of the dungeon we had to vote kick him, and we were like fine we doing without you. Thats when he said like good free drops i'm just going to be here watching netflix and a bunch of stuff.
The point is I don't care if you are myth farming brayflox HM but please don't do it on the DF and then demand a vote kick and don't be helpful the rest of the run b/c we didn't kick you. I would propose a suggestion that the vote kick had an option to put half the penalty for leaving dungeon ( 15min for me if fine ) to the AFK reason. I know is not the best option and some people might abuse it, but this thing of people demanding a vote kick to not get the penalty for leaving and then procede to do nothing and afk till they got it had to stop.
