Don't Hit What? (Pure Fighter)

Just a simple pure fighter build that I am playing but will most likely reinc to change it up a bit but figured it is decent enough to post.

Half-Orc Juggernaut
STR 16
DEX 14
CON 14
WIS 10
INT 14
CHA 6

Max Craft Armor
Max Discipline
Max Parry
Max Tumble
Whatever else is left is your choice.

Pre-Epic Feats
Strong Soul, WF Heavy Flail
Power Attack
Iron Will
Cleave
Improved Parry, Lightning Reflexes
Great Cleave
Disarm
Improved Critical Heavy Flail
Improved Disarm, Weapon Spec Heavy Flail
Blind Fight
Knockdown
Improved Expertise
Skill Focus Parry, Improved Knockdown
Improved Power Attack

Epic Feats
Great Strength 1-6
Armor Skin
EWF Heavy Flail
Epic Weapon Spec Heavy Flail
Over Crit Heavy Flail
Dev Crit Heavy Flail
Epic Prowess x5 (Convert 4 to str feats)

Legendary Feats
LWF Heavy Flail
LSA Tumble
LL Will
LL Reflexes
LL Strong Soul
Epic Skill Focus Parry
Legendary Skill Focus Parry

Saves at 60 and Geared
Fort: 64 (66 with double demi)
Refl: 59 (61 with double demi)
Will: 66 (68 with double demi)

Strength Calculation
22 (base) + 20 (level-up) + 10 (feats) + 14 (items) = 66 final
Strength with str artifact and double demi then will be 72

That means a 28 str mod so thus a 56% immune to crits.
With double demi and arti thats 31 str mod so 62% immune.

What do you think?
