Power or Regen Ranger for Roaming?
Condi regen allows more room for error. I feel this is why this is the more popular build/choice.
Power you will want to be very aware of roaming so you get full use of your range.
Power is way more fun, and a hell of a lot more satisfying knowing you outplayed someone rather than passively outhealed them.
Also it’s possible to combine the two for the best of both worlds.
I run BM Condi. It works fairly well, but I always feel hipster for using it.
Power longbow ranger all the way. Unless you always roam solo.
For solo, bunker/regen/condi/BM is probably the most reliable.
