PSA: There is plenty of AP. You just don't want to build it.

=100+80+100+125=405 AP before passives. Now, lets assume a meager 1000 mana champ. Thats 400+1000+400 extra mana from items. So...3% of 2800 mana. 84 extra ap. 489 AP before Rabadons. 660 Afterwards. 660 AP wiith 4 items and no runes or masteries.

Why is it such a strange concept that if you want lots of something, you will need to actually build for it? AD has lots of utility items now. They almost all pay for it in AD. AP is now exactly the same. No more free utility. You want it, pay for it. That's fair.

And whats more, the utility is now even cheaper. So it comes into play early. You just may want to trade it out come 50 minutes when you prefer ALL THE DAMAGE!!! (which is fair, 1 pick can win the game at that point)

Also, for those complaining about all that bursting thats going on: On-click Shield from for up too 710. (assuming the full 2800 mana)
