This nerf just seems very weird they increase the cost, ruined it mana regen early, and at level 18 it still doesn't even match the same mana regen as the base stats before. I tried it on singed and it only gave me 4 mana regen at level 18. that's horrible and to add salt to the wound you increase it's cost? WTF... It's impossible to stack it now because its mana regen is less then the early utility masterys and it doesn't even surpass it untill level very late in the game and it only goes 1 above it. How will mana hungry ad champions get mana now?
