I know literally to nothing about MW, but pve for WW/BM its easy to solo most things within 80 raids and I am close to avoidance cap with shuffle and elusive brew but taking me forever to level LW. For PvP, which is probably the reason for asking how they are, WW dies fairly easy to mostly everything but with a leg sweep can kill people within that stun. But BM seems to survive a lot longer and does a little less of the same damage.
