Suggested changes to Mana Costs and Mana Regen

[Nana]

If you lower the damage absorption deals to mana you might as well remove it entirely because right now, the mana aura doesnt even negate mana regeneration and as a I checked with someone the beam doesn't deal enough damage to be meaningful alone between casts. (I.e. you regenerate all of the mana damage between casts even if you manage to land the beam skill shot flawlessly)
