With the new big champion release intervals you can get EVERY new champion (when they get 6300IP) if you play just 1 game per day. Even with the previous release schedule - 1 per month you needed only ~2 games per day.

Yes, buying runes will slow you down but that doesn't mean you have to buy champions with RP and you only need 2-4 rune pages.
