Blue Sentinel smite buff change

Tank junglers have the Gromp buff to help their early clear, while AD junglers have the Krug buff, which helps them out before they are able to upgrade machete, these buffs are both sub optimal for many AP champion that might want to jungle. Many jungle mains recommend not smiting the blue sentinel since the buff is a lot less impactful than the other jungle buffs.

Why not change the buff to something that would be helpful during the first few clears for AP junglers, like an aura that reduces the magic resist of jungle monsters(negative MR still causes them to take additional damage) and spellvamp that only procs vs monsters, the CDR and mana regen from the existing blue buff, combined with the new effects could help AP junglers out quite a bit as they build towards runeglaive, making them much more viable.

I realize some champions could go a bit overboard with this in terms of clear speeds, but maybe having the buff amount scale with early AP up to a cap could prevent them from getting too out of hand.
