Hmmm... just a couple of thoughts that I can see with this build.
First off, are you planning on not using Mental Blast? You are severely gimping it by not socketing in Acc/Dam/ect... I see a few 6 piece set "proc" bonuses that you might want to consider making 5 and putting the extra slots into Mental Blast, which as a Ill/Rad is pretty important as you do not have THAT many attacks. I am also of pretty firm belief that you DON'T need EM Pulse and Flash. Maybe situationally it would come in handy, but I solo GMs/AVs just fine without EM Pulse. Flash just seems better to me and gives you room to take something else...
Here is a sample build from an older post on the forums that is very much similar to my build...

You might also consider socketing your most valuable power (PA) with 4 pieces of Exp ReinFMnt (acc/rechrge; acc/dam/rechrge; end/dam/rechrge; acc/dam) and then fill in with 2 pieces of Call to Arms (end/dam/rechrge and acc/dam/rechrge).
I would highly suggest grabbing Hover rather than Air Sup as well. You can get another LotG along with a nice Def Set which frees you from even more recharge that you need for perma-PA (so you can socket differently in other powers). I highly recommend staying at range when soloing GMs/AVs, so you shouldn't really miss Air Sup very much. You need to be out of their AOE range, which makes it kind of a wasted power.
I guess the biggest question for you is figuring out your own playstyle and working in the powers that you think you'll need. My strongest suggestion is rethinking Mental Blast... IMO it is very important to get that fully set'ed out, as it is a very standard power in my rotation against AVs/GMs. Best of luck to you in your endgame... if you are ever on Virtue, shoot me a tell and I'd be happy to answer...
