I could not possibly give less of a shit about your "intentions". You have made a wholesale nerf to all mages, and this is even ignoring the exchange of mana potions, crystalline flask, and Doran's Ring's regen for a base mana increase worth less than a single spell cast, the buffs to both AD carries and AD assassins that make it much more difficult for mages to do their jobs, and the changes to the costs of these items' components that makes every single step along a mage's build path more expensive.
Revert AP itemization changes. This is pathetic.
