I'm not sure if it's funny, annoying, or sad.
Probably all three.
I get in this Old Kingdom run, it's progressing just fine. On the first boss, a dps disconnects and after the boss one of the others votes to kick the disconnected person.
I didn't notice the disconnect but when I looked at their portrait, I was like "Oh, that person is grey with the little lightning" and figured that was a valid reason to remove someone from a group. It's not personal, it's practical. They're gone. We replace them. The queue was 11 minutes for me, not a big deal when my 71 mage has to wait 30.
Now, you need
The healer then asked the tank (the group leader) to re-queue to fill the dps spot.
He kept saying "Shouldn't have kicked" and "No" when asked to queue. He disregarded all of our reasoning. His line of thinking was that the person might have come back.
I pointed out that I don't like kicking people who are there any more than the next person, but that it was "pretty petty to make us run 4-man" for what we did. I wasn't angry, because I can sympathize. I was more confused than anything. Why, unless that person was a guildie or spouse (they weren't even on the same realm!), would he take it that hard?
I'm as sensitive to inhumane kickings as anyone, but that one seemed like an exercise in why the vote kick system can be a good thing. You aren't stuck with someone who goes offline.
Anyway, right after I said the "petty" remark, the healer left.
So I left.
And the only explanation I can imagine is that the tank is just very bitter about his own experiences being kicked in LFG groups, and that the bitterness makes him unreasonably sensitive to kicking anyone for any reason.
It's the only thing that makes sense to me.
