I thought they'd get it right after IGAU where both Bane and Solomon Grundy had ridiculously strong grappling skills that made you aware of the threat at all times, but they didn't lol.
They should aim in the direction of SF4 when designing grapplers imo. That game had some of the coolest grappling character designs I've ever seen. Gief, Hawk, Hugo, Hakan, Fuerte, and Abel were all scary and at the same time had unique ways to establish their game and it was really enjoyable, not only to play but especially to watch the pro players use them at the highest level.
