Personally, I see why you are saying that throwables are OP (very accurate & high damage), but at least from my experience, I think as long as cav and archers are not fixed, I rather have throwables stay the way it is right now.
An example I come across all to often:
I play berserker (because 2handers are jokingly strong), I take the throwable axes as secondary. Cav charges me and .... I'm dead. When I have these strong throwable axes, I'm at least able to kill the horse before it knocks me over sealing my faith. Sure I can swing at the horse or rider with my 2hander but I rather kill the cav before they reach me and are also able to swing at me, especially when I'm playing the berserker who doesn't have much armor anyways
