Zero Range Critical is not too good for non-Fighter main really.

Ranger side looks okay although I would personally prefer First Hit over Power Bullet - good for Shift Period in AoE.

Any reason 1pt Rare Mastery and One More Time weren't taken?

You really should get Toughness Time. When TMG gear is filled to the brim, it's one of your biggest multipliers, but so much as getting sneezed on will reduce its contribution dramatically. Toughness Time goes a long way toward preserving it. You should take the points out of Shooting Up or Zero Critical to get it, get One More Time while you're at it and invest what's left over in Chain Trigger and Chain F Bonus. It's one thing if you don't like CT, but you went all in on Chain Finish. And good god, get Dive Roll Shoot.

As for the RA tree, eh, it's okay. Power Bullet is kinda garbage though. I'd go with Moving snipe.

For Gunner:

~Take points out of Shooting Up 3 and Zero Range Critical
~Max Showtime, showtime Star, One More Time, and Toughness time
~If you're not going to max Chain Trigger, then get it to 5 and get Chain F Bonus for the reduce cooldown
