Fighter ratings

I love the game so far but there is one thing that annoys me so much. These ratings feel so out of place sometimes. How are Prates/Morales 4 stars and Bo Nickal and Chandler 4,5? How is Paddys chin only 90? I also find it weird that fighters who were known for one piece of their game have much better stats on this for example chin stats on Diego Lopes and TKZ. Outside of that I would love if there was a change in the models of some younger fighters mostly new tattoos or some iconic changes like the mustaches. It would be great to recognize fighters look from an particular performance like Lopes vs Silva.
