A lil quick breakdown to help you:

Pure DD skills
PGL: Blindside II
MRD: Skull Sunder II (great 500 TP WS with DoT to use cross-class)

Survivability skills
PGL: Second Wind II, Featherfoot II
MRD: Bloodbath II, Foresight II (Defender II in pure DD situations isn't really useful compared to other skills like Sentinel IMO)


Anyway, they're changing skills between classes in 1.19 and mostly in 1.20, so nothing is set in stone.
