At level 35 neither is worth the points to me. Points in everything else combat related makes more sense.
I’ve tried charged before and it’s not worth the extra punch on the first shot. If the mobs are in a pack or I’m trying to solo a meteor then charged is useless. Then again I’m just tooling around on T3 (and sometimes T4) worlds solo. For harder content I’ll probably adjust my point of view after experience. Even so, it still seems like a lot of points to spend for very little benefit compared to other traits and skills.
I do use damage augments always. That is too wasteful (along with durability) for rapid fire. Plus spitters and cuttles move too much for me to maximize any benefits of rapid fire.
At my level and experience so far I’ve put those points into mitigations with better results. Being able to take some hits (especially at a meteor) is worth much more than what I see as a slight damage increase.
