In essence, martials don't need buffing in classic sense. They need more cool stuff to do. Yes, your high tier 3 and tier 4 fighter can tank and dish out damage. To one opponent. While his compadre wizards calls meteor rain on battlefield. Give them whirlwind attacks, leaping attacks, stuff like that. Stuff that looks like it came from God of War and Diablo. Give them stuff that forces opponents to attack them ( in game terms, give them aggro abilities).
