A while back I spotted this link on Peter’s Blog AGGRO MANAGEMENT – TEAMWORK, ASSISTS, HEALING, AND TANKING
Somehow when you get into an instance everyone expect you already know this stuff. I suppose it’s because there’s a higher number of people running the instance for the 100th time than people running it for the first time. Even then, no one bother’s to explain about slow aggro building or assisting.
I found the article immensely helpful. Posting the link here so I can find it again in the future.
