1. The crossing problem is tied to player instructions. Some teams cross a lot, others don't at all. The problem is that the AI is too rigid. If they're supposed to cut inside they try to to that even if there's a wide-open crossing opportunity. So it's not really a bug, just a bad design decision.
2. The OS Community slider set has fixed the AI teammate problem to a large extent. Won't help you if you're an online player, but if you're a career mode or tournament player give them a try.
3. Some third kits were added. Hopefully we'll get more later.
