With everyone running around with almost zero bonus MR, mage items NEED to have their cost increased
is batshit insane broken right now. 100 AP, 400 mana, 20% CDR, GW, 25% mana restore, and it's 2900 gold.
Zhonya's is 2900 gold, Luden's is 3200, Veil is 3000. The most expensive item is Deathcap at 3800, but that item is never rushed.
ADC items suffer the same fate, but at least you can stack armor against ADCs. MR items suck dick. Maw (along with other bruiser items) is terrible. Not to mention if you do end up stacking MR, you'll just get 3 shot by the ADC.
Either bruisers and juggernauts get MASSIVE base MR increases, or APs get nerfed because I am sick and tired of immediately losing all of my health bar to mages.
