You have so many great Warriors giving you advice and here you are talking about personal play style. You CAN'T have a personal play style while you are STILL learning the job. Go learn from video guides etc. After you get to 50, THEN you can start figuring out your play style. But never go into lvl50 dg as a MRD, people would curse you for doing it. People call Warrior a lazy tank when they don't use miam combo and use def cd. Being a Warrior is not only about keeping aggro. It may when you are leveling up but after 50. If you only use Butchers Block combo then you are a lazy warrior, not bringing out Warriors full potential. I noticed that you are going full str, but i recommend you to be full vit until you get lvl 50. You can go into str after you outgear a content and learnt the basic of tanking as a warrior.
