My 2 infamy:
I took Rifle Burst-the second of the offered rifle powers, just so I could have an attack of some kind. It has a chance for knockback, decent damage, but most valuable to me is with some range enhances, it gives me a snipe I can use to pull. I don't have TP foe, mostly because it doesn't fit my character, so this is my alternative, and I don't have to open up the TP pool.
Also, I noticed you put a reduce end slot in your 'Equip' power. Since I Equip when I call up my bots, then they're good for the rest of the mission or until destroyed, I haven't found the need. it recharges almost as fast as the animation, so either recharge or end, whichever you prefer, but in my experience, you don't need both.
Keep up the good work...and happy hunting.
