About Brewing Time - if I understand it right he can switch between 3 permanent buffs and 3 all are OP:
 * - Rejuvenation Potion - Grievous Wounds is designed as a counter to healing - having a healing spell that counters the counter is counter intuitive and counter productive ( and more confusing than this sentence :). Also Rioters (designers) have stated they won't add counter mechanic that counters a counter mechanic.


 * - Molotov Cocktail - red buff that scales of 100% AD, it doesn't fit his caster theme and is about as strong as Riven's passive especially if you harass with auto attack.


 * - Insanity Potion - 20% bonus to AP - the %AP is the main reason why is one of the strongest AP items...
