So I know its not game breaking in anyway but for a AAA game this kinda stuff really should be a thing. ALL MMO's have some minor clipping issues here and there... but THIS isn't a "minor" clipping error, my entire blade is inside my legs. There's a reason Fist weapons are not liked by the majority of players and for good reason.
Yes there are bigger fish to fry with WoW Legion around the corner, but this has been around for awhile now and it drives me and probably others insane.
It took SWTOR YEARS to fix capes clipping through mounts and I don't want to see a repeat of that.
