How about this for a resolve rune?
Melee: take 10% less damage from ranged champions within 400 range of you.
Ranged: gain bonus armor and magic resistance when no enemy champions are within 400 range of you.
i would place this in the second row of the resolve tree to replace either iron skin or mirror shield, which should be combined into one rune since theyre the same effect anyways.
its supposed to reward melee champions for getting the drop on ranged champions and to fight them in melee range without getting outtraded, and rewards ranged champions for keeping their distance from their opponents and and proper kiting.
vs

which is just there.
