AP Item Changes. good idea, Wrong Time.
The tentative AP item changes currently going to the PBE are a GREAT idea Riot. It's going to promote more build diversity and make more items viable. However, burst mages are already in a bad place. Mid lane is more of a haven for assassins and poke mages at the moment. Past the laning phase, because of the tanks they have a hard time finding use in teamfights. The AP reduction will mean they will have a harder time dealing damage during this tank meta. AP mages like LeBlanc are going to love this change just as much as the burst mages. These problems should be addressed first, before you decide to go through with the AP item changes. I applaud you, Riot for trying to innovate this game, however these things should be done in an order of priority.
