correct me if im srong. i thought that the IP price of champs (ie: Jayce costing 6300) was in direct relation to their release date, not their potential domination?
It is (typically) linked to release date. The reason people say to buy 6300 champs when they're on sale is because you're getting the best value for your money since it's easier to save for champs with lower IP prices.
Heavypress. Human beings are just so damn interesting!
