Cav is too easy to play right now. Nearly no drawbacks, except cost.
No damage from collisions ... no damage from falls ... delivers damage just bumping, even failing charges ... no exhaustion... light horses get no damage from bumping ... NO DRAWBACKS AT ALL, even the logical ones (collisions, falls, autodamage from bumps). Besieds, you fall from your horse and you're a full health infantry ... cmon!!!
I agree that cav should be overpowered when flanking, but right now they're superior in every circumstance, you have a horse with 1hp, and you can charge full speed, charge somene, fail but still bump him and kill him ... surprise, your horse didn't die ... ridiculouos
Just 2 or 3 changes in that way wouldn't nerf the class completely, just make it to be played the way they should be. Good cav players don't have to be afraid, cause they are already doing it well, it's just the noobish cavs that should be afraid.
