Oh yes, plenty of times. Majority of them is from pug raids though, and the reason is always the same.
Last time I was kicked from a pug it was Immerseous normal I think after 1 attempt. I play healer and I have done so since the beginning of the game, I'm pretty good at what I do. On this particulat attempt I was designated to a side that had players that knew not to stand in stuff, and at the other side of the room was a disc priest who had people near him that didn't know to get out of shit. After we wiped becuase people died the priest linked healing done (I was probably bellow the tank for reasons described above) and the leader raged at me. I explained what happened on my side and that he can't expect a druid healer to out-do a disc priest 20 seconds into the fight with the circumstances we were presented with. I got kicked for being "bad" and talking back.
This is why I don't pug or play with casuals.
LOL, you've seen that I've played for a long time, as far back as vanilla, so you should've at least put together that I know the whole "wait for sunder armor" debuff, hell I used to be bear tank in BC so I know the wait tid bit w/ stacking 3 lacerates and having Omen/Addons that tell you when you're close to pulling aggro; in fact we were forced to practice waiting in raids with my BC guild otherwise we would not get loot. It's obv me.
OT: Ele Shammy was kicked from Flex 4 for dying to the poison debuff from Siegebreaker trash twice. I popped all defensives and started healing to help the healers but no dispel, if I could've I would've.
Been kicked many times. Trying to remember some memorable times.
The number one time was a raid for VoA. The RL was looking for tanks, so I told him to invite me. He said "MT or OT?" and I said "I can do either". He repeated himself, as did I. He said "your not tank?!?!?", I replied "yes I am a tank, I can do MT or OT, it doesn't matter", to which point he kicked me. He went back to trade saying "LFM Tank for VoA". I whispered him to say that I was a tank. He replied "your tank?!!?" and tried to invite me. I told him to fuck off and put him on ignore.
I've been kicked from more than one LFR for suggesting that people who don't bother to try should be kicked, which is met with the usual "omg its just a game, u elitist!". I'd try to explain that I wasn't asking the world, just that people don't afk all the time, or auto attack all the time. "ITS JUST A GAEM!!". I learned my lesson now.
Lvling my shammy as resto, I used to top the DPS meters whilst doing my healing job, got kicked a few times for it. I'd understand if I was letting people die, but I think it was just a lot of butt hurt.
For those kicked for ninja pulling, GOOD!!! Pet hate of mine.
If you have never gotten kicked then you have never played wow....true story.
