It just depends on how you want to play. Crit and evasion are luck based while dmg and defense are more consistent. Your current build would work fine for stats.
For envoy, it becomes a lot trickier. There are subclass combo skills all around the edges of the board that you want to pick up. So having an idea of what your subclass choice could affect the envoy choices to get to that skill. Personally, I am just going dmg + crit rate + crit dmg envoy's. I just made my Gunslinger, so I haven't decided on a subclass yet, lol.
