with zero ironflesh, you will realize you die quickly. So i recommend you not to give any pt skill. Here is my current build;
Level 30 (4 420 577 xp)
Strength: 21
Agility: 15
Hit points: 70
Converted: 2
Ironflesh: 7
Power Strike: 7
Shield: 5
Athletics: 5
Riding: 0
Horse Archery: 0
Power Draw: 0
Power Throw: 0
Weapon Master: 5
One Handed: 146
Polearm: 6
Equip also a pike, awlpike, or a long awlpike instead of throwing weapons. It will give you advantage against cavalary
He is right. Here is what I think about common builds:
18/18 : Weak in strike, too much usage of agi points on shield, athletics and etc. Go for it if you are a ninja
21/18: Too much converted points, you waste them instead of using them for ironflesh or so: you die pretty quick
24/15: Too much converted points again, and again you die quickly. And your damage only increases about 4 points or so.
21/15: If you give your points like the way Reyiz said, then you have a descent 1h+shield character. Rest of your success depends on your ability to fake your attacks and chambering.
Also I still could not observe the speed difference between 1 handed weapon proficiency of 5 WM vs. 6 WM. Also there's only 1-2 points of increase in your attacks when you have full 6WM based proficiency. Therefore I stick with 21 str and 15 agi.
