[Suggestion]: New AP damage oriented stat

** First of all, why this?**

Because I think that the main issue that AP items have (most of the AP building the same items, lack of armor/AP or QSS/AP items, OP items that needs to be nerfed ruining other characters, Mages dwelling into Support oriented items, etc.) is that Ability Power as a stat is too generalistic. AD champions cha choose between raw AD, Penetration/CDR and Crit/Attack Speed builds while AP can go for Ability Power and Pen/CDR.

Which stat then?

Name is a WIP but I was thinking about somethin like: Spellweaving. SW would give bonus as you cast different skills in chain so that not every AP/Mage can effectively use (Cassiopeia, Karthus and all the ppl who have a spammable ability won't benefit much form them). Which bonus this gives is something I've not thought about. It can also give different bonus if the character using it is categorized melee or ranged so that we can give different things to Assassins and Mages.
