FB/FA is way better then RT. Afaik RT is giving 20%DMG and FB/FA 30% (or something like that).
FB is only vyn so we dont be able to get it as BL.
long story short, nobody wants RT on his weapon and that makes it useless. Would be nice to have a buff on that cast. so that the WL/BL weapon cast a bit morw even.
I know there is still BT, but not everybody like to grind that up. with mobs its a pain and with alts its maybe fast, but when the body stats drop to low on the alts, it will not work anymore. plus you have millions corpses laying around at the token.
RT wounds are useless too, never saw someone dying from that. I think its even more a downside that the RT wound stacks to the blow, instead doing an extra wound.
(dunno how much DMG Venom is doing, but I never saw someone useing it. only the bypass of the glance rate is nice, what ever it means)
