I think they're a great idea but replacing the defensive/attacking movements with these makes it awkward.
So I change my formation at the start of the game. I can't be bothered to go and do this another four times for all the other presets, but this now means that in game I can't switch from balanced to attacking, because then it's going to change my formation back to the default one. So I either have to enter my formation five times before every game with slight variations (looooooooooooong) or just ignore the d-pad strategies all game.
Won't be a problem in UT when you'll presumably be able to actually save these presets so you only need to set them up once, but when playing against your mates in one off games and stuff, that's going to take forever. Or you just can't really use 'attacking' etc. Unless I've got it wrong.
It would be great if, once you've set up your formation, there was a button saying 'copy this formation to all presets' then you could just go in and change the tactics for each accordingly, that would be way quicker.
