Fantastic seminar! I've had my Nrg/Nrg blaster since the beta and your words are golden.
I think it should be noted that you can pretty much avoid the 10 sec post-Nova downtime by just eating 1 Blue and hitting CP, that usually gives you enough to continue blasting at near (kind of) full capacity until your 10 sec are up (provided you have stam and whatnot).
Also, I have Stealth and Invis right now, I swear by stealth, but rarely use invis, can you expand on your Leadership vs. Concealment?
