Unless pvp against a melee character.
But for pvm its useless, even with a level 50 spirit of the barbs (1030 percent damage returned) and a level 50 thorns aura (2210 percent damage returned) and a level 50 Iron Maiden (1425 percent damage returned) for 4665 percent damage returned and a monster that makes a 100 damaging hit (wich is high) that would only give him 4665 returned damage, if he hits ofcourse wich is something anyone tries to avoid, he also has to hit melee, ranged and magical doesn't work.
Now say it has about 15000 hitpoints, then he needs to land a succesfull hit atleast 4 times.
In pvp on the contrary, it can quickly decimate any melee character, even a spirit of barbs at level 10, thats why its most then not frowned upon in pvp.
