Now that I have a courser, HA are less of a problem.
Pikes only start to show up when I take a pike myself (tested)
Less throwers than *before* (vaguely), so I have less things to worry about than *before* while riding.
1h leftspammers are ugly and stupid, and can't manage a good hold. It's just very boring and tedious to fight them.
2h agiwhores are irritating when they pretend being pikemen, but I got used to that.
Polestagger abusers I'm ok with. This mechanic is needed in group fights anyway. But GLA/whatever hiltslashers are still ugly and stupid.
Plate + crushthrough guys are my logical counter on foot, I can run away from them anyway and furthermore they are easy to kill from horseback.
In the end, the classes I dislike "fighting" are xbowmen and bowmen, because I never actually "fight" them. Either they shoot at my horse and it dies in 2-4 arrows/bolts max, either I backstab them. And I explained why I hate having to kill archers when I'm on foot in another thread.
