Exactly, that just seems like a huge oversight. To make up for this I think it'd only be fair to give him Erron's 21122 and all the ticks that come with it
Exactly, the design of a character is how they act. Erron acts like a grappler, having numerous tick throws, as well as other types of character due to having pressure, mixups, etc because that's how the designers wanted him to be implemented. Commando acts like a defensive variation as it has parries even though it was probably designed more to be a grappler which is harder to be because he doesn't have that many ticks. They designed Kano to only have ticks off of pokes, F33 and jump attacks but that design was implemented by the developers/programmers...but that could be argued all day and isn't the point. At the end of the day throw immunity is a thing, some characters have throw immune moves that have a few throw immune frames and it's just something that's a part of fighting games. Throw immunity isn't what hinders Commando though because most people probably don't even know what moves they have that are throw immune right now, it's (combo) damage and/or lack of significant ticks that makes this variation slightly less effective.
Well firstly I've never seen a single Kotal use D1, D3 or B1 as anti-air tools so I wouldn't say those were anti-air tools but I didn't say AA normals exclude grapplers from having a grab, I'm just saying Kano having multiple anti-air options is probably the reason why he doesn't have an AA grab. Up Ball always works as an anti-air for me but if it doesn't work for you then fine we can just not use it but it
is designed as an anti-air tool, effective or not.
