If manouveability n speed are reduced charge and hit points should be increased. Else cavalry will be an expensive joke.
That is for sure.

But to be honest I don't see why horses needs a nerf in any way. If anything, armoured horses needs a buff. Both a decrease in cost and an increase in stats.
If horses are soo fast and manuverable why not increase the running speed of infantry and arrows? That would be a better option.
No matter what FPS game I play I rather play at high speed (or with more damage dealt and taken) than the opposite. It's simply more fun, challenging and competetive.
If I want a slow game I just play a turn based game. Oh wait... Maybe that is the solution?!
Why nerf the speed little by little with every patch, let's just make it turn based already! 
Speed nerfs excluded I think the game is more fun and balanced than ever as it is right now... just don't make it even slower.
