I like those. For me, I think my dream addition to CM right now would be an advanced chemistry system. What is more important in building a squad and their performance than chemistry?
It's such a shame that UT has this but CM doesn't, though what I'd want would be nothing like UT's. UT's is unrealistic and not particularly deep, whereas chemistry's potential use in CM could be pretty deep.
I also really miss the days of manual player growth/player training, though I understand some people don't like this idea b/c it's not especially realistic. I'd still like some type of hands-on training feature. Something.
Another huge one is overhauling team management so that it functions better, has deeper tactical options, is easier to use, etc. This also should be combined with more in depth planning approach to upcoming matches. It sucks we're given practically no information about our upcoming opponents.
