Can this work? Archer c1 ranger C2 Wugushi c2 and fletcher c2?
Taking Fletcher C2 at Rank 7 isn’t the optimal choice. I think you are building a DoT am I right? Oh and might want to leave Ranger at C1 and take Archer C2 instead you get nothing worthwhile at Ranger C2 for near end game.
For me leave either Wugushi or Fletcher at C1 then pick the Rank 7 class of your choice.
