Rune that increases blue/red buff duration

Replace Waterwalking in sorcery with a rune that increases blue/red buff duration and grants AP while you have either buff.

Don't think it should grant AD too because it would by abused by red buff users. Similar to how conqueror does not grant AP because it can be abused by mages. Red buff is a very strong combat buff already.

Waterwalking is just adding to mobility creep for no reason. This new iteration has a better jungle/river interaction
