User blog comment:Sagee Prime/Nunu... and the future of supports/@comment-5418658-20120820084843/@comment-3323227-20120821004701

I wasn't aiming at blatantly nerfing nunu although I find him to be quite too strong at the moment. But I think other supports need some buffs and that Supports are being wrongly nerfed in their damage areas because of their utility. My solution to even things out is to go ahead and nerf Utility by an acceptable amount but give abilities that supply utility Utility Scaling. The rules with Utility Scaling is it cannot directly increase your damage except in special cases like Janna's Shield and that the abilities must fall in the category of Buffs, Debuffs, and CC.

Buffs being Hastes, Shields, and stat boots

Debuffs being Armor/MR Shreds, Damage reducers, and sight trails

CC being slow% and Blinds, Charms, Fears, Silences, Snares, Stuns, and Taunts duration

Each of these will have a rule with the associated scaling, some will have a cap, and this stat will be made unattractive to champions seeking to do a lot of damage. This means most itemization will lean towards the support role and shy away from damage but some damage items will gain small amounts of UP due to their team support nature like aura items (Zeke's, Aegis, DFG, and Abyssal Scepter)
