Multi-Strike and Annoyance are going to be cheap due to being uncommons. You can't move slots around due to when they were placed in the build. If you slot something at 29, you can't magically reslot it at 34. You need to start from the beginning and go from there. Of minor note, I have no idea why the slot for the +KB protection is there. More when I see two major issues with the build.
1. The current Recovery - End Drain is .7%. That's outright awful, and more so for a build which doesn't have a click power to refill its end bar. Likewise, regen is 216%. On a tanker. WTF? I have a EA Brute which will sit at over 500%. I feel like I'm missing something, but that feels incredibly low for a Tanker.
2. One of the best ATO procs to the point of being broken is the proc for Might of the Tanker. It isn't in the build. Fine, you want to skip the rest of the set, but how negligent do you need to be to forget that?
