Should charge attacks be unique for all weapons?

I've noticed that the weapons that Rezoner adds keep on getting more and more diverse, and base statistics themselves are being altered, something that never happened with axe/hammer/sword. I got to thinking how each weapon could be modified and made unique to the other weapons, and the charge attack seems like a great route.

So, I've drafted new charge attacks for each weapon. Hope you like them.

Axe: The player pounds the butt of the axe into the ground as if trying to plant it. has an immediate range, and does 1 damage to knocked over players. The target is knocked on to their feet (for balance purposes). Does not effect standing up players.

Hammer: Basically the standard charge attack as it is now. The hammer is swung in a circle and the player moves forwards slightly, but less than it does now.

Sword: A lunge. Right as it is about to release, the player stops moving momentarily. The lunge is a significant, but not ridiculous, distance, about the same distance as the old charge attack. This lunge does 2 damage, and 1 damage against blocking opponents, however, it is prone to disarming by kick.

Spear: The spear is swept along the ground in a 45 degree cone in front of the player, dealing 0.5 damage and knocking over opponents. Can be countered with jump, and the knockdown can be avoided with roll.

Claws: A grab/throw charge attack would be perfect for this weapon. Does 0.5 damage upon the grab, and another 1 once they hit the ground. The target is thrown behind the player, and knocked down upon landing, unless they dash before landing. Can be countered with standard attack, and only inflicts the grab damage against roll (you can't throw a rolling player).

In addition to differentiated charge attacks, I feel that each melee weapon should have some 'passive' stat differences. Spear and claw already have their stat differences, so why not add some for the others? in order to make these balance changes work, weapon swing arc should be reduced to 90 degrees across the board first.

Hammer: a heavy weapon that should do significantly more knockback, so it has more potential to deal bonus damage when the opponent is launched against the wall. it also should have a very slightly slower swing speed (10% or so slower).

Axe: a forgiving, reliable weapon that swings in a wider arc (160 degrees) than all the other weapons.

Spear: Already has a longer reach, but should have a narrower swing hitbox arc (should be reduced from 90 to 60 or so).

Claws: Already do less knockback, should have a slightly lower reach (15% or so). Also should have a swing speed 15% faster than average.
