I've got also some decent legacy nat gear, however right now im seriously considering to buy new nat + mempo for pvp.
If someone tells that it give so much advantage, he probably never played with legacy nat. It is good @ ava, when 1-2 shot decide of win.
But really, in comparsion to new set, about ~25-35% life and ~30% damage loss isn't that op.
If somebody want to figure out, PM Me bt, I will show the difference.
For me banning this set doesn't make sense..
