Model O is cool, but not necessary. What is needed is to revamp Model ZX. I remain to this day firm in my belief that Model OX is, functionally, what Model ZX *SHOULD* have been if not for game balance, due to the curse of being the game's basic form.
-Model X needs long hair, matching that of its user.
-I'm thinking we end the alternate time shpiel and have Aile/Grey be the legitimate timeline. Have Vent pick up Model Z and we can work something out to re-introduce Ashe (Model C?).
-We demand 2-player co-op for story, preferably over wifi.
-Hu/Re should have a Chain Rod type sub-weapon (no charge attack obviously) in order to work around its lacking a wall-kick. It gets very annoying for those looking for the challenge to have to switch every time a high jump is needed.
-Model PX should have the option of using the sub-weapon button rather than the touch screen for its seeker kunai, in which case auto-target the nearest enemy. Also, use Mandala Star as the extra charge attack, the shield blew.
-LX should have a second, wider halberd hit on the ground (not 3 hits, we don't want the melee fighters feeling cloned), and this should allow greater fluidity in the ice platform/sticker moves (Ice Dragon remains the top charged attack).
-More trans-ons need to be able to get around walls (Hedgeshock, Shisaroids, looking at you).
