How about the old headgear enchant for range damage boost, is it worth it?
The only worthwhile headgear enchant to invest into as a Ranger would be ME5, and that would be purely for Aimed Bolt.
Yes you can get increased damage by going for the Bow Master or Acute enchants, but no it isn't really worth it.
The investment for a Level 5 Enchant alone makes it just not worth it, the RNG to get that enchant is just as bad sadly.
Prior to OCP, a single item giving 50% Crit damage would be been fan--_--tastic, but now, it barely adds 15% overall damage when coupled with all the existing OCP items we have (and this isn't including the new ones coming tomorrow which again do some good -_-).
So yeah, aside from viable end game Aimed Bolt I wouldn't recommend investing, unless the fixed the -_- that was this god damn crap enchanting system. Even then, I would be iffy due to the investment price, much better to save up for an MOT card; or better yet, not care at all since everything dies quickly with what we have.
