Personally I like the way aggro is handled in this game way more than in WoW and many other MMO's. In WoW it was so easy to hold aggro as a tank that you didn't have to even try, pretty much you had it and nobody is going to take it from you. In this game you have to actually put some effort into building and keeping aggro and in my opinion actually having to work somewhat to properly fulfill your role is a good thing. I'm also glad for the most part that aggro management is not solely up to the tank but the team as a whole, it makes people need to pay attention to what they are doing instead of just spamming all their abilities without a thought, although many still do unfortunately.
