Firstly, the pet. Op? Why dont you try it in pvp and tell me. Nekro beat it hands down always unless the player is a nub. Then again, compare their AA's too.
Secondly, you said the ring is OP? Well heres the thing bro, yes it might add some good hp or mana(from a rogue perspective) but whats the point? The damage provided is crap and cant even beat a legendary vigo ring.
So please think twice before saying something is OP.
