I've been a huge BoP fan for those very reasons. As leveled up though the Battle Cloak seemed to lessen in its usefulness. At higher levels using it to run will most likely get you killed. It was nice to recloak instantly after a fight but its a minor loss. Personally I think everything should be able to battle cloak. If you want to drop your shields and cloak then do it. You never saw the Klingons say ok wait a few minutes and then cloak up LOL. You drop shields and you cloak end of story.
