Me when:

People on another class tell me how I should be playing MY class (unless its actual advice).

People attempt to 'punish' for not playing to their standards.

People derp for the lols but don't care about the 23/7/3 others just trying to get thru this.

People expect more from the group then perform less.

People can't listen/comprehend instruction. Or care.

This is when I'm a bad player. But imitation is the finest form of flattery so, *shrug*.
