I keep Tactics on all the time and frequently get BU procs. I know Grant Cover doesn't work on me; SD seems geared more towards teams than solo, so I figured having that and Leadership powers would compliment that idea. Do you think it's worth slotting Health/Physical Perfection to compliment True Grit? I tried to do what I can with Hasten, but the most is does is shorten Build Up's recharge by 5 seconds, and that's usually recharged by the time I move from one mob to the next.
