It's pretty much useless to talk. Nordeus is one of the most selfish companies, I've to "deal" with. There were a lot of (good) suggestions. To tell only a few things about the mutant issue:

-) engine has to penalize 1% attributes. This is the best example ever
Let that mutants run like robben, but without dribbling, shooting, they never can score such a goal.
But what did Nordeus? A "stupid" cap
On the otherside, cap was the only possibility with an engine, where attributes are useless.

-) Cap was suggested, but with 400-500% long ago, before Nordeus ever thought on caps

-) capped skills should give the % on not capped skills...

There are a few more good suggestions.

At the current situation it's the worst solution they could do:
-> you lost a lot of % and greens, if a skill reaches cap
-> cap is too low for losing skill points
-> with the current drills, where you have a lot of passing on there, it's stupid. Nearly all my Mx, AMx and ST have passing at highest skill, because I try to train them balanced...

This season, I didn't watch 4 of my games (for me, that's a lot), because the motivation drops at every new patch...

A year ago, there was a game, that made me addicted, but at the current state, I think every day, if it's worth to keep playing. For me... that's really sad, how Nordeus turns that addiction to boredom and frustration.
