NEW Clarity. 80% Mana back!
People are talking about diversity in Summoner spells. I always thought that the cooldowns should vary based on the spell a bit more than they do now. But that's besides the point. How would it be if Clarity gave you back 60-80% if you were alone or the closest ally has 80% or more of their mana remaining. That would make it more viable and it could give mid laners sustain in a tough assassin based environment.
