yes .. there are some, a bunch of hint's, guide's & build's spread over the forum (fun-builds, cav-guide & so on.)
as for myself ...i play with an' alt as a pure jousting lancer with 9 str / 27 agi / 172 wpf pole / 8 wm / 9 ride / 9 shield / 3 ps & ride with rupert my courser in fast, wide angles & circles, use my roundview-cam a lot (holding right-mouse) to dodge ("a" & "d" & speedcontrol "w" & "s") incoming cav's , arrow's , rocks , walls ...& finally pick up a target/opportunity for a hopefully successful hit.
maybe 12/24 - 15/21 ...4-5 ps ...6-7 ride , heavy/great-lance , destrier, courser, arabian, some like speed , some like manoeuver, some durability - it's up to you. i'm not the experienced lancer-cav player.
probably one of the Great Khan (GK) dude's can give you advice, or other experienced lancer's.
edith: ah well .. Johammeth has enlightened me ... who told 'bout [C]avalry! ?
anyway.. maybe it help's you.
