You seem to be 2 over on 6.25% recharge bonuses, so the slotting for Disruptor Blast and Summon Tarantula aren't doing much for you.
I went with Primal Forces over anything else, because PBed Fade + Group Invis is just too good to pass up (~30% defense to everything for everyone on the team, as oppose to 16-17%. Throw in another ~7ish from Shadow Fall + Maneveurs and you're hitting 36/37 to anyone squishy). Pity the rest of the set is urrgh, although at least Energy Torrent takes Forced Feedback. One slot left in Spectral Terror for the Energy Font proc. I suspect overall I could go more Proc Monstery with it.
Here's a my non-purp build, most of which I've gotten slotted up already (I'm level 45 currently). It might be useful.
