I don't think a melee character is sacrificing efficacy by staying out of melee for as long as possible by guarding the ranged character. If the ranged character can stay out of melee and avoid taking damage so can the melee character, and they can use a readied action to attack an adversary that survives the ranged barrage, as well as an opportunity attack if an adversary tries to bypass them and go after the ranged character... I think we're ultimately getting stuck in an agree to disagree scenario here, because my judgement is that any encounter that all the characters survive is an equal success by both the melee and ranged character. Additionally, I think this is boiling down to a difference in how we approach the game, in that I think that a character that only utilizes melee is deliberately handicapping themselves and should not have the rules changed to benefit their decision. In my mind a "melee character" would be versatile enough to utilize thrown weapons prior to engaging in melee, thereby making the difference between a "ranged" character and a "melee" character more of an aesthetic difference than anything else.
