Emophia isn't entirely off. While this is a game, there is a system of Officer/Subordinate in play and Mr. Vent was out of line. The subordinate failed to recognize his own faults and make a proper attempt to correct any problems. He then proceeds to tell the raid leader how to do his job. Mr. Vent is the catalyst for the drama not the officer.

The conversation would have gone better if Mr. Vent just stated the fact he did his best to communicate his trouble and wasn't given the attention needed to sort it out.

Next time try this...
"Hey, I tried to communicate my trouble but no one would speak to me or give me a chance to sort it out. I'm sorry for my part in tonight's frustration. I'll sort things out before the next raid and prove myself to be a good raider."

In three sentences, you've stated your problem, resolved your own mistakes, and confidently asserted yourself without being offensive.

That being said the raid leader that night was in fact lousy. He/She should have approached Mr. Vent to discuss the trouble. If not when Vent asked then after the first couple of wipes.

Both sides are at fault but Mr. Vent is "That Guy"
