As the topic title says, I'd love to be able to take shield defense as a sentinel. A few restrictions would probably have to be put in place, (perhaps not allowing dual pistols, assault rifle, beam rifle, or archery), but otherwise there really shouldn't be any issues - Tankers, Scrappers, and Stalkers can get various blast attacks via their APPs/PPPs, so that precedent already exists. The set would probably have to be modified, like others, though - as much as I'd love to keep shield charge, this would probably be dropped in favor of some sort of end recovery power, and I could see grant cover or phalanx fighting getting replaced with some absorb click power. Your thoughts?
