Hey! One of the things you'll notice most is that your blaster knocks back almost everything it hits. This can be good or bad, depending on the makeup of the rest of your team. It's absolutely amazingly powerful solo build. If you set up your powers according to their attack range you can walk yourself up and down your power toolbar like a piano, destroying onrushing mobs as they come at you, or obliterating an adjacent enemy until he is out at snipe range for the finishing blow (although rarely does anyone last that long). You have a couple of melee attacks that do stun damage. I recommend that you maximize their accuracy and stun durations. You have plenty of other damaging powers that you don't need these to do damage, so take advantage of that stun secondary effect as much as possible. Other than that, try hovering instead of running. The added altitude will give you an excellent perspective to apply your AoE attacks to maximum effectiveness.
Oh, and a combination of Aim and Build-up with Snipe will one-hit kill anything orange and below. How can you NOT like that?
Have fun and I hope to see you around!
