To answer the assumption that I'm doing the bare minimum I will say this. I am performing my role. I heal and dps. however when I continually get tanks who can't hold aggro or use cool-downs its a little difficult to do two jobs at once. I get comms I'm saying that people are increasingly just leaving the instance without so much as a tyfp.

Secondly I almost never go without leaving a comm. I've always felt that is was polite but I guess that was a misunderstanding on my part as well
