AP in general

I will talk about ap users and their itemisation. The reason for writing this thread were the syndra nerfs (higher base damage but lower scaling). When i read that, it came to my mind a similar event on a larger scale in the past. When riot tuned down bases on utility on supports, but gave them scaling. So here is my idea. Make supports scale off ap more and make it cheaper/added on more support items (i particulary like how athenes works now). Also turning rabadon into an item for supports when they are ahead (keeping the passive). But wouldn't that break mages? So here is the followup. Nerf their scalings and buff their bases like syndra now on pbe. Then make more magic pen items and make mages "scale" of that. Of course they would still buy ap, but not as much. And it would discourage going mage on bot as the support items wouldn't be as effective (the ap part). Of course that should be done during preseason as it is large scale work. K i'm done now. No tl dr as it is short enough read.
