I know when I play I won't be paying much attention to the animation but the subs look really dumb when there are a ton of steps to them. Of note to me are the armbar (where they stand crouched over the opponent holding their arm for a weird amount of time, and even worse is the heel hook, when it started Jones was standing there holding Gus' leg, no movement/struggle from either.
They just look wrong when most UFC submissions happen more explosively, like you slap on the submission, then maybe you fight for it a bit. Or you get into the position without it locked, then BAM locked. I think the chokes are decent (except the absurd angle of the leg around the body for the peruvian necktie) and the shoulder locks look good. Another weird one is the mounted triangle/armbar, it looks fine except for the second step, where the leg isn't under the head yet.
Personally I prefer the way the subs look in the last UFC game. Also while I haven't played this one yet I don't really liked the look of the new minigame. While the other one wasn't great by any means I really felt like I was trapping them in it.
