I'm not sure what the next huge patch will give Goro, but I do know some buffs I'd like for the big guy.
F2 being faster on startup. F214's buff is made better with this and stuff like F212+4 -> D4 xx PW to bait mashing out or just using one of the 3 strings attached to this button is more viable. Also, either speed up his D2 or increase the horizontal range of U1/2 so he has a consistent meterless AA. Even with the buff given to U1/2, I feel like AA-ing with the move feels like it's in the same category as trying a cool, impractical combo online in terms of ease of executing it. Those are the realistic buffs I can see happening that I'd like. The stuff that's probably not going to happen but I/probably other Goro's would appreciate is a different story.
Increased movement overall. This means less floaty jump, walk cycle speed up (startup of walking is actually really good, so leave that alone), slightly less recovery frames from dashing and a run that's actually usable. Goro can get zoned out hard by the likes of Kitana, HQT Pred or anyone with competent zoning, ESPECIALLY if he has no meter. This statement might go against what some people may think, but this is Goro's biggest weakness at the moment imo.
Buff command grab so that it's easier to tick off of strings instead of being able to tick only off of a single normal. This would make him stronger in offense obviously. He doesn't have 50/50 potential or guaranteed pressure like run cancel characters, so just increase his ability to tick throw.
those are the buffs I can see being possible/the buffs I'd personally like to see for Goro once KP2 releases. One or two of these changes being implemented is enough to help Goro out imo, aside from fixes like what Gruff mentioned about his F4. Here's hoping we get something.
