Well, let's start with the basics. You are getting 3 more powers but have basically no slots for them unless you steal from other powers (since you will presumably slot up the inherent fitness to the same levels).
A simple solution is therefore to take three powers that require no slotting and possibly rearrange powers into a more exemplar friendly build. There are four powers I can see that would fit that category:
Vengeance (always nice to have and you can stick a 5th LotG 7.5% in it)
Recall Friend (another nice one for teaming and you can stick a kb protection IO in it)
Tactics (even slotted with just an endurance reduction IO this is nice to have on t`he Incarnate Trials to help you hit the +3s)
Summon Disruptor (you've got enough global recharge to have it up a reasonable amount even unslotted and it makes a nice distraction while soloing, stick a Nucleolus Exposure HO in it so it gets some Damage and Accuracy)
So the simple version is select 3 of those, rearrange powers to suit your tastes and maybe see if you can steal a slot or two from somewhere for Tactics and/or Summon Disruptor if you take one of those.
Other alternatives, such as taking Fighting, would comprise a more significant rebuild.
A while ago I was looking for a good Assault Rifle/Traps build and I have found one. However, before I found that one I was directed to a thread that could help me. In that thread was a good build. The only issue with said build - is that it is from before Fitness became inherent. I was wondering if anyone could teach this old build new tricks.
