Bass is actually really good but requires a certain degree of patience. Once you get his vortex going, he is in control and can stay in control for the match. But yeah, i9 jabs will be annoying as fuck though.
He's not hard to use at all. He's like Ein or Rachel for instance, easy to use, challenging to win with if your opponent is smart.
Bass + Ceiling = Guaranteed 70% He is such a good fuckin' character. Irritates me when people consider him low tier.
