The Cait buff woulf be extremely OP. She already has a strong early game, buffing her base damage and scaling on Piltover Peacemaker would cause ger to do ~150-200 damage at level 1 with it. Her ult is very powerful anyways, though I do think the reduced damage for an intercept is a good idea, I think nerfing intercept damage instead of buffing overall damage is a better idea.

On Lux, her ult already is really powerful and an range increase would make it much closer to global than it should be. The addedn scaling along with the scaling on her passive would make her early damage rediculous, essentially giving her ult with a combo 155% AP scaling, on a spell that long ranged and with that much base damage already.
