Just because a lot of people prefer it? Or do you actually have a reason that it's overrated?
people tend to think immune makes them more tanky in pvp when in fact if you're at least a half-decent player then you'd use a converter on all your skills which can be endowed with an element. noxious>raydric for pvp, unless you know you're tanking pure neutral damage. as for pvm, go with raydric if you cant afford dr of course no arguing about that.

hmmmm i dont actually get why a lot of people default woe sets. i only find woe sets useful for swordsman/thief/merch classes. yes stacking demihuman reducs is nice but sometimes there are things better than what the majority considers as the best. maybe its just my play style but meh.. my sura can reach 71k hp without tao (only 50ish% demi reduc tho), non-tao woe set wearers can't do that
