Playing around in mids' I've started thinking "if I'm going to have maneuvers & the shield wall unique in a build I might as well have them together" my new slotting philosophy is 3 shield wall IOs: def/end+5, def/end/rech+5, Res Proc & then add LoTG Def/7.5% Rech(+5 the LoTG if it makes sense to you but it probably won't outside of a defender or tank since they get the highest base value from Maneuvers)
Should knock maneuvers end use from .39 to .26 or so.
Edit: fixed typo from buy to but
