Jax's Grandmaster's Might with lower Mana cost @ Lv.1 that ramps up at higher levels?
I was thinking maybe Grandmaster's Might should work like this as the game goes on:
Start at 70 Mana at Level 1, Go to 85 Mana at Level 2, And finish where it sits at currently for all three, but instead have it only demand 100 Mana at Level 3.
Would this be too much of a buff? Should the numbers be slightly different?
