-Yes, but I know I am whiny person, I am ok with that. You seem to lack that understanding about yourself.
-The random ice mage or the tank that tries to only dps and dies, they could learn their class a bit better.
-I am glad that you know your limitations. I don't need to worry about myself, it's all muscle memory at this point. Also, again, since you don't seem to understand, We are not talking about little mistakes or occasional wipes that take a certain amount of scrutiny to notice, we are talking about overt blatant problems, like trash packs taking double the time to kill, tanks who can't hold threat off of a healer, and players who don't know anything about their role/job.
-If you lose your sh!t over someone not saying hi, then maybe you should not be on the internet. Find something that better suits your need to be socially acknowledge.
