That's actually a nice idea. Maybe split bonuses into half and full.
Might +1 Fortitude
Con +2 Fortitude
Intelligence +1 Will
Resolve +2 Will
Dexterity +2 Reflex, +2 Deflection, +1 Accuracy
Perception +1 Reflex, +1 Deflection, +2 Accuracy
Arguably Dex and Per could both affect evasion and accuracy so why not split it. 15 Dex and 15 Per would total +15 Accuracy +15 Deflection which is pretty huge, so the other stats should have as big an impact on combat. E.g. high strength could be a requirement to be able to punch through medium/heavy armor in which case a high Dex/Per finesse type fighter would suffer against heavier armor and/or have the Endurance of a fly. Strength should influence the success of knockdowns and shield bashes and whatnot heavily too.
Intelligence is already a dump stat for melee warriors so it would only become more important for everyone if it affected the number of skill points you get.
Resolve could play a role for non-casters influencing how much and often they can use active talents (encounter powers) like knockdown or disciplined barrage. A resolute warrior could be more versatile and have more control options and answers for particular situations on the battlefield.
This is what im talking about!
Resolve should be (is) mental strength. It should be important to characters like wizards and paladins.
