I found a low ethereal windforce on season - 3161.4 dps, +10 discipline, 44% reduce resource and a low 164% multishot damage.
Is the 200% to archery skills on the windforce enough to make up for the 200% MS on my yangs and the extra 164% multishot on the windforce is gravy on top?.. If not, is my old yang’s better?
If you do not salvage them before the season ends, they vanish, lost to memory.
[edit]
The only thing you can retain is their appearance (transmog) but only if you Pokémon them (find all 21 individually named Ethereal weapons, 3 for each class.)
I’d go this route. Yes, that’ll mean losing 100% uptime on Vengeance but with Captain Crimson equipped and enough CDR on other gear one can reach reasonable amount of uptime.
