Something that always bugs me (doesn't make the game worse, but I don't understand) is why they always advertised the game as air-combat focused, and yet give us so few air moves compared to the ground ones, and also you get a lot more style points for basic ground combos.I like Bay's (Bayleef's, haha) soft lock-on and auto lock-on. What I didn't like is the fact that it felt like there were too many moves you could do. The original DMC series (mostly DMC3-4) had it right with quality over quantity in moves; except for DMC3's Vergil gimped moveset in my opinion, and DMC4's enemies being made for Nero more than Dante and it felt like Dante was disadvantaged at times.
Bay's moveset was more or less in my opinion, mash buttons/remember some combos, get Wicked Weaves, win. Also, dodge/perfect block-dodge-thing for Witch Time. Ninja Gaiden sort of did this too except it had no lock-on whatsoever unless you're using projectiles.
DmC on the other hand seems to suffer from too little moves. While they may be efficient, it gives us, the players, too little options. God of War had this too right? I don't remember since I've only played III and that was about a year ago.
The style meter is just broken though so you can disconsider the last point.
And yeah, Bayo's combat, although great and one of the best ever made, is not in the same level as DMC 3 and 4, unfortunately. The game overall is fantastic though, and I think it's a better game than DMC4, even though the combat itself is not quite there.
