Cant see your build right now.. But if you have 45% in all your defenses / positional types then your golden.
I would do a search for my name but look up a thread by Ratero I think. I might have his name wrong. That is why I mention do a search for my name on these forums. But Ratero pretty much did the defining build for Robot Traps. I then kicked it down to the cheap end. Granted going cheaper lowered many of the regens and other bonuses but it still stayed within the tankermind constraints and further I run the build so I know it works in standard tankermind fashion. The difference is mine is running +1 +8 with ease. So easy that I fall asleep sometimes during a solo farm and wake up with the mobs around me cleared or logged out but alive. Ratero build would probably do +2 +8 with no issues and probably +3 +8 in similar fashion.
You mentioned travel powers. I will say this, if you can afford the 10 bucks for ninja run, I would say get that booster pack and buy a jet pack in grandville and your pretty much covered.
Travel powers are so early 2k. 
I can see the day that they just finally concede and just allow players to pick up travel powers without taking up a actual power slot. At this point it really does not have any effect on the game. If it did everyone would be using X travel for some sort of game advantage.
Nutshell compare you build to what is already out there.. No need to reinvent the wheel when someone did it for you. You will know if your build is good or not when you start looking at others.

I am posting this build to see what i need or lack and how to make it better.
I want to be able to solo, have good recharge, and be able to help a team by being able to maximize the potential of all the traps. I don't care much for the heroic APP's, so i just picked one. If some of the powers suck or some are awesome that I may have missed, lemme know. If there is better slotting, id like to know also. I would like to be close to the soft cap for as much defense as possible without gimping the build.
Flight is his travle power by concept. I know this build will cost alot. I avoid purples unless a set of 5 or so make good sence in a power (like maybe switching out the ones in fireball for example).
