Good idea! Making adjustments. . . Also, I will use it instead of a Trident/Spiked Shield for my piercing weapon.
Human: Power Attack (I'm keeping this)
Fighter: Exotic Weapon Proficency Spiked Chain
Level 1: Improved Unarmed Strike
Level 2: Weapon Focus Greataxe (I don't know why, but I am keeping it)
Level 3: Improved Grapple
Level 4: Weapon Speciallization Greataxe
Level 5: DOdge
Level 6: Mobility
Level 7: Spring Attack
Level 8: Greater Weapon Focus Greataxe
Level 9: Melee Weapon Mastery (As a prerequisite for WEeapon Supremacy)
Level 11: Combat Expertise
Level 12: Greater Weapon Speciallization Greataxe
Level 14: Whirlwind Attack
Level 15: Improved Trip
Level 17: Improved Critical
Level 18: Weapon Supremacy
(As you can see, my fighter is weighed down a little, as he has a greataxe, a greatclub, and the spiked chain along with his longbow.)
Now, not only will Gregory the Fighter be free from those "Roy has boobies" jokes, but will also dominate the battlefield. Thanks for the help! (If you have any more suggestions, please tell me).
