RIOT, before the upcoming rune page sale, let's talk about rune system (probable) update direction

Hello. So the runes and rune pages have been a topic for a while. RIOT-ers have mentioned they consider some changes on it so I would like to know a little more about direction of these. First of all - the idea of the player having a bit of control over his champion base stats stats since the begging of the game is pretty decent, and I like it a lot. Having some control over that helps both surviving unfavorable match-ups, lane/jungle sustain, snowballing or whatever a player choose. Then again the system have a few problems, mainly it's cost. For the 10 rune pages I had spent something like 30 000 - 40 000 IP, and I had bought them mostly in sales. As we all know the amount of IP we earn per game someone could imagine what it is for a new player to fill the rune pages.

However I an mot making this thread to complain, but more like to ask. RIOT-ers have stated multiple times that they would work on improving the rune system. However - what kind of direction these changes would be. With the upcoming rune page sale, and maybe with runes sale after that - would there be a reason at all to spent IP in runes/pages right now? This have been bothering me for a while, could you please clarify it a bit?
