Like 15% on cast? Or how about if you spec into the mastery for it, it gives increased mana regen when it's on cooldown?
I'd love to see this for mana heavy junglers like fiddle and mumu.
Let me know what you guys think about this idea.
Very good idea.
Maybe a free mana potion on the use of smite, +150mp over time, make it replace the +10 gold on smite masteries.
Although I'm on the fence about removing the +10 gold, junglers can use every bit of gold they can put their mitts on.
