Giving the fighter reach for free over other classes is pretty broken IMO. One of the only reasons to take a paladin is because he can mark at a short range, allow fighters to do it and you might as well play a fighter multiclassed into cleric for the same thing, only better.
Plus, allowing fighters to have reach free is sort of working towards the 3eism of having 8 different weapons on you, each for a different job (I did this! An archer with cold iron, adamantine, silvered, and various enchanted arrows, plus bludgeoning and slashing backup weapons, and a piercing melee weapon too i guess, etc...). This lets folks who chose to specialize benefit even more. You can already attack at reach, allowing OAs at reach, especially for a fighter, is super powerful. you essentially lock down a 5x5 square of the battlefield, and if you hit they lose their action. You get a bonus to hit equal to your wisdom.
Mebbe I am overreacting.
