Threat Problems as a warrior
I've been tanking since I first created this character and have done a number of normal 5-mans in vanilla WoW. I skipped most of the BC ones because I was leveling too fast and I didn't need the gear. Once I hit WotLK, I began tanking again because I knew I'd be doing them on heroic difficulty later on.
I tanked fine through the normal five mans and upon hitting 80 and the 540 defense cap I started hitting heroics hardcore. The first couple runs went well, including one where I wasn't defense capped. By using a combo of cleave and thunderclap I was able to keep aggro through most trash pulls of 3 or 4 mobs and the bosses were never a problem except for the beginning.
Recently however I've been getting into groups with dps that have raid gear and I have had some serious problems keeping aggro on trash pulls of 3 or more. They just simply do too much dps for me to keep up with. On the bosses I had no problems keeping aggro, except when the warrior did whirlwind on one of the bosses, took me a bit to get the adds back on me.
Is there some technique I don't know of for aoe tanking as a warrior? I know we aren't that great at aoe tanking but I don't even have enough time for target switching and hitting each mob consecutively with a high threat ability and then cycling through them till each is dead. Any suggestions?
I was about to post my armory link but it still thinks I'm level 71. Will have to wait for an update, but I'm currently at 547 defense with almost 23k health unbuffed. Any help would be greatly appreciated. Thanks :)
