This looks nice and cool.
Hopefully this will influence all gameplay and move it towards a rock-scissors-paper-ranged-cav style of play like Joker mentioned.
I'd like to see 1h remain usable as a class where the whole blade does the damage. I do believe there's no need for a rework on this class, it's pretty balanced altogether at the moment.
2h could be more oriented to playing with range. For example, the hitting part of the longsword is actually the 1/3 of the whole lenght, rest would have even been unsharpened. However, gameplay wise this could probably mean something like full damage for 1/2 first part of the blade, 60% damage for rest.
Polearms would need a rework. I'd like to see polearms as a support class; they are slow and cumbersome but either hit like a train or polestagger the target.
Archery is quite balanced at the moment. All the twohanders crying about it should realize that archers are meant to counter them, so they should be able to kill you.
Crossbow needs some sort of skill imo, it's very easy just to grab an xbow and use it as a shotgun. This is silly.
Throwing is throwing, it's a melee support class like polearms.
Cav is a tricky situation. They are basically mounted footmen, since every one of these classes also work on cav. I believe the key with it is to work on the horses. They should really hit hard, getting trampled should leave you only with like 50% HP. On the other hand, if they really caught a spear in the chest they would drop dead or reduce the movement speed into running level unless they'd have massive armor on them. If possible, perhaps a "Bonus against cav" tag for some weapons?
I can easily see a problem with this though, since people would just go as a twohander because they want to be the super action mega rambo hero who slaughters the whole enemy team with his superior greatsword. There is not so much glory in playing as a pikeman who is poking the enemies from behind as the twohanders stack the kills (hopefully some day we will see damage inflicted to enemy team as a score meter instead of kills). This would lead to a situation where cav would be superior to all inf, just bumping them down day and night since there wouldn't be enough polearmers to stop them.
It is quite tricky, and whatever devs decide to do with this, they have a lot of work ahead of them. I'm still willing to help in item balancing if needed :-P
