Dual laser blades (projected from the wrists) like the raptors would be cool, and would fit in well with the fast paced action. I would change the blades to something like a cyan colour to match Naked Jehuty.

I mean...
I wouldn't try and make the hammer so slow its unusable in the fast pace combat...
People will just need to figure out how to use it differently.......

Different people would use different weapons...

ANd I also see potential if I could time the swing right and reflect a charged blast.....

THat would be kinda hilarious

Speed is definitly awesome.....
THat doesn't mean it will be sacrificed for both players though... just one person....

claws

wolverine.
Big Bear...
Aka Ursa Major

I can haz Jehuty with two swords instead of one?

I think I know something better!
How about a few more combos with the blade? How about a kick at the end of the slash sequence. Let's all think back to the final battle between Dolores and Hathor.
Wouldn't it be nice to do what THEY could do? Better yet, how about using the right analog stick to control the slashes with the gesture of the joystick? You could create a more dynamic attack if a physics engine was involved too, which would allow you to knock your enemy this way and that. But with the right analog stick concept, you could do a "Slash up, Slash down" or anything that your power-greedy heart desires.
AND TO TOP IT OFF, hold the burst attack button while quickly slashing up and down to cut the enemy in half! I want the fightscenes to resemble Idolo's final fight scene as much as possible!
To make a bonus character in the multiplayer, it would be nice if they added the chararacters from Dolores too. I wonder what Dolores is capable of in the game...(daydreams)

I see what you mean- so, a melee system like Devil May Cry? I remember when I played DMC 4, instead of using the button-mash combo, you could get a different one by using (attack)(short pause)(attack)(attack) or (attack)(attack)(attack)(short pause)=(super attack)
I bet Kojima could do something like that

yes you can, but we can't have 2 users using the same style of typos here.
this world is too small for us both so
here have some blade tomfaa

An energy/laser like sword like Halo 3's energy sword, Now THAT would pwn.

Scythe from Gundam Wing would look cool.
It feels like you're the boss.
