I had a little go on it last night. It's all very unfamiliar and probably a little unfinished. The tactics looks like a bit of an improvement (I haven't played any games yet).
I did find a bug. I was trying to set up a 3-4-3/4-3-3. I needed what would have been a halfback on the old game so the WBs could push forward. Every time I set the player to CB/DM, he'd revert to Target forward/DM.
I'm not much of a tactical revolutionary but if I can find someone like Fellaini (but good), with the stamina of prime Kante, I might just give it a go.
