I love the idea with the prime skins/helms being able to work on Umbras! But the Exalted Melee getting points from its stance mod? That's what Formas are for. Stance Mods giving points are just fancy ways of saying "You wont need as many Forma for your build." Just gotta grind some Forma and POOF, no need for Exalted Stance Mod points >-> They can't give us EVERYTHING, that's also another one of the successes of Warframe, you have an endless list of things to do, LIKE FORMA'ING EVERYTHING!
