I'm currently a 24/15 shielder with 8 power strike, 5 iron flesh, 5 shield, 5 athletics, 0 weapon master totalling about 30 weight - it's a perfectly viable build providing one's footwork is good and one knows when & whom to engage, will one shot most light to medium armour users with speed bonus, drop heavier foes in three to four hits with a 34 cut weapon.
Not great for chasing archers but excellent for soloing mobs.
