Cavalry have to backstab people, which is pretty stupid. Honestly, they're useless (they fucking have to be at this point) in strat. YES, they CAN get MANY kills if they're skilled in battle, but the point is that those kills are peasants, afk's, and people who aren't paying attention.
As far as archers, they're not useless. I see archers doing well all the time, but it's JUST LIKE CAV (as far as the nerf thing). They have to kill unarmored targets (usually) or get insanely high pd. Honestly, archers are fine as is imo, but probably because I'm a cav player who gets shot all the time. ;)
I think that crossbows are needlessly OP. Why does everyone complain about archers? They're killed by projectiles. Crossbows, in the state they're in, add WAY too many projectiles to the field. Yes, I understand about medieval warfare encompassing all types of weapons, blah, blah, blah. But balance is definitely an issue. Scare off the masses of xbow users by slightly nerfing crossbows. This will help cav and ranged as well as melee players.
As far as 2h/pole goes, I've been stunlocked by a few weapons there. They're also EXTREMELY FAST. While I know it's not just a 2h/pole problem, pure builds with these weapons are a bit too fast and strong in my opinion.
As I'm sure others would agree, this game is reasonably balanced, but could use some work. I hope at least one person will take the time to read this and reply.
