Riot, I really used to like your IP cost reduction on champion prices

How the cost for older champions would go down every time a new champ was released

But this was only introduced when you made the move from a new champ every 2 weeks to a new champ every 3 months.

REALLY OLD champs like Rammus, Anivia, Kassadin and even Olaf are still 3150 IP. Galio is 4800. GALIO

Every champ after Ziggs, who was released over 3 years ago (Feb 1st 2012), costs 6300 IP.

IMO, your price reduction should go from every champ release to once every Month. Instead of when a new champ is released, the oldest 6300 IP champ goes to 4800 IP, and every 3rd release a 4800 IP champ goes to a random lower bracket, it should look like this;

Every month, the oldest 6300 champ is dropped to 4800 IP, the oldest 4800 champ is dropped to 3150 IP, the oldest 3150 champ is dropped to 1350 IP. Every 3 months, the oldest 1350 champ is dropped to 450 IP.

This way, people who are new to the game or who don't play 24/7 can still build a champion pool without farming forever. Between this and trying to get runes and rune pages, its ridiculous.

TL;DR Champion IP prices should be dropping more frequently
