[Sarinpa1]

Spirit pain only affects basic attacks and as far as I know, doesn't have a 100% assured chance to work.
Tested on 1v1, opponent was gun wielding, single shot. First shot that round triggered spirit pain, second did not.

So the cost, the fact you can bypass it by everything that doesn't use basic attack (Impossible only with MG, as far as I know. But you surely have a subclass. Or multi-shot weapon. To bypass that. Right?) and that it doesn't have an assured proc chance.

I don't agree with a nerf.
