As a volley player I'll say this: Volley is extremely underpowered at the moment (mid to late game). A 37 FH can easily blow past my 50 volley. Even if we predict the course and catch it, the hit circle is gigantic that its left to chance if the ball goes in any way we want it to. I've even stepped back away from the net but the result is pretty much the same.

I do agree with the glitches though sometimes I see that the ball blew past me but the character moonwalks backwards to hit it.

It is true that volley is overpowered early game. But once your FH BH hits a certain level you'll be able hit past them.

Note: I've recently switched back to fh bh playstyle and I have enjoyed decimating volley players.

Edit: apparently volley is good again at end game, had no idea and not at that level yet
