Vel'koz and the mana numbers
So, if anyone hasn't noticed yet, I'll be honest, the mana seems considerably low for all of his abilities. Maybe increasing them by 5-10 mana per level would fix this issue. I tested out using Athene's Unholy Grail and I never ran out of mana. Another thing maybe to try would be lowering the base mana per level. Let me know what you guys think.
