Back in the days, while cRPG was still popular and populated I enjoyed my STR balanced pitchfork peasant (real peasant gear, no looms, level 30). It forced me to play better and was quite enjoyable, didn't frustrate me a single bit because I knew I was at disadvantage. Right now, that is pointless. Not enough players for such a thing.
Only thing you can do right now is to utilize your high level char if you have it, make strong cav build with best +3 gear and couch everyone, when they dismount you, use warhammer. The little bit that has been left of this community will cry and you will enjoy it, because they are cunts and deserve rape from rich high level troll who's bored of this mod.
18/24 should be good build for that. Don't need more PS because +3 Warhammer is a beast of a weapon.
