Ok so, i used to tank in xi, but this is not xi. I seem to be having issues with keeping hate in even the most basic of fights so i was wondering if i am missing something here.

I use provoke, shield bash, war drum, and sentinel. I was going to go out of my way to get the marauder enmity ability, and taunt from pug. However are there any other skills i should get? Oh, shield level is 50, and glad is 45.
