Diana w mana cost.....

Her mana costs are pretty reasonable, but Flask is a good start for her since sometimes you have to use W defensively without getting off any damage in return (you waste more mana than the opponent).

In my noob opinion, I say try to hit the enemy with your W bubbles more often to offset the cost.

Not saying she can't use a little Rito power to bring her up a tier. I think E is a better focus for buffs since it is the worst part of her kit.

I'd like this for my jungle clear with her, but i can't complain about how it is now.
