I just want to say that I have enjoyed reading this guide very much, I had started an Energy/Energy Blaster once but found I lacked the knowledge of the powers to make my first Blaster useful beyond being just canon fodder for the mobs. So I started all over again from scratch. A couple of notes though, I noticed on several build plans that they didn't use stealth or used it very late in the build, to me that was a mistake, I took it at level 6 and never regretted it, the same goes for Build up, I took it at level 4. My biggest reason was that if I went alone into a mission with a known Boss, I wanted to get rid of his cronnies first from a distance with sniper shot and then build up and sniper his buns from a distance, you'd be surprised how fast they drop afterwards. My second reason for taking those two early was if I helped someone as an explar, guess what I still have my big power boosts to keep me alive and help them make it much smoother in the end.
Another note, the power called Energy Torrent, while I do plan to get it, I haven't yet, at lower levels it will agro the heck out of everyone your tanks and scrappers haven't aggroed, and guess what ? You've just been turned into a pile of goo and someone has to either rez or give you an awaken to get you going again. Wait on this power until you reach a point that you can Torrent them, then get out of their range. The Lost with their mind monsters and lizard looking thingies, I forget their names, can't use those powers if their on their butts most of the time. A suggested, mind you I said suggested, would be to use knock back on the power slots to insure they hit the ground. Embarrassingly enough I do have a badge that says I've been held by them for an extended period of time, I blushed 3 shades of red when I suddenly got that badge.
Another note to those who claim SS is a good idea, try running through fault line with only hurdle as your alternate travel power...it takes forever to get through it, I tried it and even with stealth on my side it still took time. I raced a team mate of mine to find the exploration badges and the plaques found in the zone...I lost and they waited for 20 minutes at the gate. They had Fly, the cheater (LOL)
Anyways that's my take on some of this, but the rest is on the money
