spinning back kicks and flying knees can be stopped mid execution

Could anyone here tell me how it is physically possible the opponent can stop your spinning back kick and flying knees when you execute them cause the last I checked that has never happened in an actual ufc fight in real life ea seem to be focusing on adding new fighters and not fixing the real problem I mean the changed the way you have to perform a parry and that just opens a window for them spammers so you cant even have a good time playin the game really needs sorted out ufc was one of my favourite games to pass time till these stupid updates came out its pretty much made for spammers and not for the people who enjoy it as I've seen from release online had at least 25000 people playin now its dropped to 5000 anyone see the big difference here and the players dropped down when the 2nd update came out so work out that it is the worse ufc I have ever played and regret even buyin it if I had of knew ea would bring out updates that would ruin it like that I wouldn't have bothered paying the money for it and I have been playin ufc since 2009 and the game was great the way it was there was no need to change it at all
