There's a few things i'd change.
You can slot Membrane exposure HOs in Active defenses, it'll improve your def debuff res plus recharge. double stacked AD is great.
I'd put the plus Rech proc in something that recharges faster
I don't run Maneuvers for defense, it's so end heavy for what it is.
Touch of fear with a bunch of procs seems off to me, i skip that power unless somethings changed since i last ran that set.
I also don't take Grant cover.
You have slotted 6 LOTG 7.5s but 5 is max.
I can build my version if you so wish. my mains FM/SD Scrap
