I pretty much murder cav players except the really good ones with 2hand thrusts, and always scan around me (rebinded look to E), and focus on baiting cav by faking unawareness or manning up and 1 vs 1ing them, sure it's not very hard.
Doesn't mean that mounted heavy lance damage isn't at an astronomical percentage whenever they post the stats, and that in my testing with people like BADPLAYER a non loomed heavy lance will nearly black bar medium/heavy infantry with 2 powerstrike with a small arabian warhorse speed bonus.
I'm not the greatest cavalry player either and suicide my horse into shit all the time attacking aware polearmers and the like when I'm cav, but with half the effort I require as a melee class I can pretty much roll a 5x for hours at a time with little to zero support from anyone else, just by how damaging the lance is and how versatile in support a well ridden horse can be for your team.
Also, cav spam on the servers is awful, only thing worse is thrower spam, and the two feed off each other. So nerf both, please.
