It's not like catching kicks is the only counter to them. It's just the most annoying one to be on the receiving end of because it takes control away, which is the same problem parries had in UFC 2 tbh. If you straight up removed the kick catching mechanic (which I don't want, to be clear), you could still back dash away from a kick and throw a counter kick or duck/lean into the kick to armour it and throw a counter combination. If they just make the counter punch on a caught kick do less damage it would encourage the takedowns from the caught kick more and the riskier counters for more damage.
