Not in order of importance...
1) They took away the option of home/away shoe colors while editing player gear. Also, they limit what colors you use on certain areas.
2) Limited selection of Nike ID shoes, and there are one's that aren't in the "ID" list that say "ID", i.e. Nike LeBron 9 ID.
3) A bug where I edited the KD IV "ID" assigned to KD... view Durant and he has blue LeBron 8's on wtf lol
4) Can't take away a sig skill once added to a player. If someone has 5 and you don't like how they play, I'd like to subtract.
5) No VIP profile, and can't dl sliders.
Notice that none of my issues are with gameplay, which to me is great. The problems I mentioned are a big deal to me though, and I'm sure others. If these things get fixed I'll go buy another copy and give away to someone who wants it.
