Physical items are way better than AP items
Ever notice every single AD champ rushes
. Hmm, I wonder why. One full extra ability worth of damage added to your next auto and all you have to do is touch a bush. wow.
What do mages have to rush? Oh, they have to build mana crystals because if they don't, they'll run out of mana. Hmm. Seems fair.
AD champs get massive damage, armor pen, lifesteal, ridiculous critical damage, on-demand move and attack speed. God forbid if a mage opponent has any potential to fight back. No problem, we'll just make sure AD champs can build
to completely counter the mage and make absolutely sure that no mage can ever defend themselves.
Just compare AP items to AD ones. Most AD champs are either manaless or have extremely low mana costs on their abilities so they can get items to help kill the enemy. While AP champs are stuck getting items to try to make their abilities useable or less crappy.
There is an obvious favouritism towards the AD champs with very few exceptions
(which are not really mages but assassins with AP damage). Most AD champs are simply way stronger than AP champs because they get way better items.
AP items need some beefing up.
