The kicker, healer, and 1 other dps voted yes.

I think they are a majority vote. Someone got kicked from a group I was in the other day before I had even voted.

I was in one group and the kick passed with only 2 votes. The vote was to kick the healer due to some abusive language. The healer was in the same guild as the tank, and I voted no since the run was going fast and I can ignore that crap, so I voted no, the tank voted no, and the healer I don't think gets to vote. And yet, the healer was kicked. The tank then became the party leader, kicked the person who initiated the vote, and reinvited the healer and we got another DPS in 5 seconds. Pretty comical actually, but pretty lame that just 2 votes to kick passes the motion.

I thought they were unanimous too, but I think that Blizz must have changed it to account for scenarios where a person queues with a friend to just drag them along.

Something that annoyed me once with the kick rule.
Was just starting a run and someone got disconnected and didn't come back after a decent wait, so someone voted to kick him. It passed and we got a replacement and went on with the instance.
A little way in someone else was acting like a prick and I go to vote to kick him, but that is when I learnt that you can only kick one person per instance (or something similar).
It annoyed the hell out of me and in hindsight I should have asked the leader to kick him though I can't remember if he was the leader or not.

It has to be 3 out of 4 I think (since the guy getting voted on doesn't get to vote).

The really amazing thing with the story about the feral druid being kicked is that Belt was obviously a dpser in the group, and the druid who was kicked the other dpser. So for the vote to pass, both the tank and the healer who died would have had to vote the druid out. You'd hope the tank would notice when a healer dies and put 2 and 2 together (spoiler: it's 4), but what's really mind boggling is that the dead healer voted him out for low dps.

To deepen the level of douchiness presented by this situation, note that the healer who died voted to kick the DPSing druid who took over the heals.

It's not that surprising to me that the healer would help kick. My main is a resto shaman and I go enhancement for fun. One night I was running Forge of Souls normal and heroic for enhance gear and THREE TIMES in one night the healer dies (various different healers) on the second boss and I have to heal with my pittance of spellpower. I make a joke about it afterwards and the healer tells me it's "better than nothing." Yeah, it's better than wiping cause our healer stood in the well of souls and didn't heal themselves.

When healing I try to be good about noticing hybrids who heal themselves or help in really ugly situations, but some healers don't notice at all.

actually, I've noticed that some people don't even consider what they're doing when that vote button comes up. They click "yes" because it's what you do. A terrible thing that I had to break myself of after the LFG tool came out.

It's important to think why someone is being kick but it's hard to discuss sometimes when you can't whisper. That's why if I have to ask why someone is being voted to be kicked, I vote "no."

You can whisper others in your random now, while you are inside the dungeon. I have.
