Suggestion: 50% sale on all the champions for a limited time for the 2015 season

As we all know that one day later Riot is going to do the Extra Bonus RP thing. So, If I speak for myself I'm going to buy 7900 RP in order to get some champions that I want to play and main, but the problem is I don't want to spend 975 RP on a champion which will go on sale eventually meanwhile I don't want to wait for too long either because I want to be prepared for the 2015 season.

My suggestion is that put all the champions 50% on sale for a limited time so instead of waiting for a champion to go on sale we can buy it earlier and be prepared for the 2015 season.

I'm pretty sure there are hundreds of thousand people waiting such an event like this.
