Finishers also provide alternate super energy consumption. I definitely abused the hell out of the special ammo finisher when I didn't have access to the right helmet element for ammo finder last season. I wish they'd make power ammo finisher a normal mod instead of tying it to seasonal artifact. It's already expensive as hell in both mod points and super energy... I don't think it beats any of the other final tier season mods except maybe from the depths.

Finishers offer both a good design space that they can attach interesting effects to in the future, as well as an acceptable monetization space. The pricing on it is a different discussion altogether, but I'd say I value cool animations over cool skins so in that regard, I am a more willing customer and do not begrudge them. They are cosmetic in a purer sense than ghosts shells, which confer minor grind advantages, which adds up and rubs me the wrong way.
