A bit of advice i learned myself, not all too long ago, is for starting a pull, Berserked overpowers makes for one hellova giant emnity gain, easily sticking a whole pull to you for most if not all of a fight. At this point i try to keep as many skills on CD as i can while effectively managing what i feel i would need. need the quick emnity boost? internal released or bloodbath, berserk, throw out some overpowers. hate is sealed. higher lvl you need some dmg cushion quickly? vengeance + foresight is a nice, quick bounce in your damage reduction. just 1 huge thing to remember, no matter the level of content youre at, is if its humanly possible for you to dodge an AOE, do so lol. very rarely will you run into AOE you cannot dodge. so put every effort you have into taking less hits.
