Thread Title:
Aetherflow starts cooldown but doesn't add Stacks used for casting spells which requires aetherflows.
Basically, in random situations, usually after another instant cast spell (Ruin II), Aetherflow fires, trigger its cooldown but doesn't recover mana and doesn't give you aetherflows (3).
This is a huge issue, basically destroying summoner dps for 60 seconds.
