Yeah, it's only a matter of animations so far (although I don't see the dash attack as weak, so it will probably really close to Link's). When semi-clones share moves and don't play the same way, we can only expect Hero to be different!I hope he uses his shield for F-Air or D-Air, I want more shield moves, lol.
Animations are not the end all be all. Depending on their hitbox, angle, knockback, frame data, Eerdrick's run speed, jump height, fall speed, air drift, moves will be used in completely different ways.
Regarding the possibly missing spells, I see a mention of Heal. I believe we've not see this animation in the trailer, and the effects are those of healing items. Does the pose looks like healing spells in DQ?
