Corsair - WS/RA/QD Sets

Quite new to this job so I wanted to ask for some advice for my sets.

This is my Wildfire set



Aside from the +2 head, are there any better pieces? Don't plan on doing the missions for the body.

This is my QD set



Denali legs and mab rings from tahrongi I guess? Does the +1 head provide extra damage?

This is my RA set



Aside from +2 items what else should I get?
