With the enmity buff to overpower you should only need a couple uses of it on group pulls to hold hate. If you can get the Maim buff up first you might be fine with a single overpower and then single target.

on trash mobs you will eventually have inner beast and paired with vengeance that will be fine. On a single boss is where SP debuff will be used as you will have time to get a lead on enmity. Late game you will find that with single target keeping enmity is fine with just SE SP after starting with a couple BB.
