Wow! Amazing thread for its detail and options. I was already using power burst with the jousting though I didn't know it was called that because it's the only real way to get the blast off and not be in melee range long enough to get hit. I would like to add that my favorite opening attack has to be snipe, but when I face a boss, it's total focus all the way. My god that power is awesome! I have it six slotted, five damage, and 1 accuracy. What I like to do is use aim, joust the boss with total focus, use power burst, power blast ( hopefully still with aim up), then hit build up and snipe, by this time the disorient usually wears off so then I use whatever blast is up, and that usually finishes them off if not sooner. I have noticed that I can take on bosses like this without them even getting a shot off. The disorient on total focus is amazing almost 100% if you hit...some bosses resist albeit rarely, and that damage of that attack is insane.
