I guess something I'd really like to see would be to have graze disabled during bombs again, as it was in IN and earlier. I think a lot of the bomb grazing in SA onward was pretty retarded. It pays off way too well to be invincible to things that you wouldn't be able to graze if you weren't incincible - see Parsee, Unzan, midboss Ichirin if you're not a fukken badass superplayer, pretty much everything in DDC (a lot of this is due to cancelling bullets with your bomb mind you...), Yuugi's final, etc. It's so awful and yet it's so profitable. Bombing for score is one thing but I think the new games take it too far sometimes.
