So heavy armor, stealth and hide as a non-class skill, smite ability, high hit points, etc. don't give incentive to face the big evil head up as opposed to say spending an action to try and sneak up on him and most likely failing miserably or attacking from range with a low Dex??
No they don't. The only incentives around here are anti-incentives. "You are either in theory or in practice not allowed to do this so don't do it." If the fighter can get the ambush they should, and rogues should very seldom waste actions for Sneak Attack.
Unless of course their abyssmally low hide and move silently scores negate that
In short the only reason they shouldn't is because the class tells them they can't. It's sound tactics. And if they can whittle the enemy down at range safely the fighter should do so.
This is a very different situation from "We know this is bad tactics but it is in character so we are going to make sure that it works better."
