the fun part of tanking st is to be mt and grab everything and hold it all... scare your healers pray dps is quick enough and look like the monster tank you should be....
same for wod.. although youll die more often.
seriously though.. if your grabbing hate and holding it on half the trash your doing your job right.. and no you wont keep hate on everything cus you have 15 dps trying to steal the show...
