I hadn't had so much fun until I tried the build Cora recommended to me, which I have been enjoying for two generations: 18/21 at level 30 with 140 2h wpf and the rest in polearms. Half-swording is finally useful with this build.
I'm going for this build now:
Level 32 (17 784 806 xp)
Strength: 21
Agility: 21
Skills to attributes: 10
Ironflesh: 2
Power Strike: 7
Athletics: 7
Weapon Master: 7
Two Handed: 130
Polearm: 127*
*WPF calculated by the Planner isn't exactly correct (it's a bit less).
What I don't know is what I would do at higher levels - go for riding or for 24/21 / 21/24.
