Drat. Striking those feats would drop 1 damage, and 1 from both AC and Reflex.
Couple options:
1. Start with 13 con and 13 dex, and pick up Axe Mastery at 24th. Have to forgo Plate for awhile, though.
2. Swap Con for Dex and trade the three Axe feats for weapon proficiency: bastard sword, armor specialization: plate, and blood thirst, picking up Heavy Blade Mastery at 21st. You lose the gee-whiz of the big crits, but you gain +1 attack (from the higher proficiency bonus), +2 to damage on bloodied foes, +1 AC, and a higher Reflex defense.
3. Go dwarf. Start with 18 Str (at a whopping 15 points), 14 Con, 15 Wis, 12 Dex, everything else 10 or 8. Add TWF and TWD after 11th level. At 28th level you'll wind up with 26 Str, 22 Wis, 17 Con, 14 Dex. Since Plate, TWF, and TWF won't be available at Heroic, take Dwarven Weapon Training instead. You'll lose on AC & Reflex, but gain on damage.
4. Start with 15 Con (for plate at 2nd level, and default 17 con for axe mastery at 21st level) and 14 Wis. All stat bumps to Wis. Skip TWF and TWD. Spend feats on Plate Specialization (+1 AC) and Lightning Reflexes (+2 Reflex) instead. You're a net +1 Reflex and -1 damage.
