I was recently lmpqing, and I was kicked because I was a cleric. Someone literally said "Kick the clerics, man. They're slowing us down." Is this allowed?
Why would it not be allowed? Its up to the party leader to decide what is best for the party, and if he kicks you, well just look for another or grind if you can't find one.
Not against the rules, but I agree that it's not very nice. If I used my equipment on a cleric, I'd probably out damage some of them, but that's all in hindsight. Just grind at Ghost Ship 2 until 80 and leech until 120.
