You can add any mage you want to compare. You will notice that the average cost of Anivia's abilities are by far the most expensive of any mage. Combined with the slowest projectile speed, and relatively long cooldowns, Anivia is handicapped early game. Consider that the average game length has been severely lowed the recent seasons, Anivia never has a chance to shine anymore. Her early game needs a lot of help in the form of lower mana costs on all her abilities.
W and
E should have low mana costs compared to
's really strong and game changing abilities.
Is why she has ZERO mana issues
