Yeah, like I enjoy the intended functions of mana, energy, and other resources, but I never felt like Riot truly got a handle on how to balance it all out properly.
I personally dislike blue buff because several champions, particularly mid mages, are balanced around the belief that they will have access to it. Well, turns out that's not a guarantee which led to the need for Athene's which then led to, etc.
I'd much rather Riot re-evaluate the need for either blue and red buff. It would be neat to make it a team wide buff of some sort.
