Although I cherish your video input a lot (never new horses could descend like that, woha!) you are missing the point.
-this is not a nerf thread, au contrair: it is a thread which is seeking for answers in how to making horseriding more skillbased. All in all that will result in a buff for dedicated riders,
and only a nerf concerning the easy part of being a cav.
and this is the part where you should chip in as an experienced rider!
Yeah. I did see some suggestions however that seemed like they'd ruin it for me, so I kinda knee-jerked it a little bit.
I have to go to work soon, so this will be a bit less long-winded. As a kid, I'd wager a good amount of people played with whacking piƱatas on birthdays. In my family we did this on horseback, and granted this isn't proper lance practice, but we'd use staves and spear/whack the things as we raced past. I'm sorry to be so contrary in my posts, but I disagree that speed = shouldn't be able to attack. The faster the horse is going, the easier it is to ride in fact. Once you hit a gallop, it's a four-beat movement, and it's like floating on a cloud IMO. Really smooth movement.

Heres a suggestion. Maybe the more riding points you have, the wider of an attack angle you have?
