I think a "Jujutsu" (as in Japanese jujutsu and not that brazilian jiu-jitsu junk) set would be more appropriate secondary for Blasters and Dominators. Locks, throws, and joint manipulations make a pretty nifty canvas for a manipulation based secondary that fits nicely into a Natural origin context. Certainly, the Devs would have some animations to tweak and build but it'd add a lot to the game
