I just started playing the game on Friday. I am up to level 25 marauder. Didn't realize there were roles or what the roles might be. Haven't played any kind of MMORPG in a long long time and also made the mistake that I was all about DPS.

I don't know what half of the abbreviations in this thread mean yet... But I did get my first "congratulations on being the worst tank ever" comment last night. Lots to learn.

Can someone explain what Aggro means?
