Runes Reforged: Kleptomancy Is Too Generic
Aside from a slight gold boost, it's randomness and vast pick list of consumables it can possibly grant you make it far too generic of a keystone. Even for a Support it's pretty meh since there are othet Keystones that give direct access to helping allies rather than gold. It's only really decent on Ezreal and Gangplank, and even then it's VERY mediocre. This is mainly because it's power is really generic and doesn't provide a straight benefit to anything, which is what keystones typically want to do. I would think it wise to focus it on a certain kind of consumable or straight up gold generation. The state of it right now just makes it really meh on everyone.
