Runes and their lack of practicality

So riot has finally address the issue with runes and their implications to the game. They have admitted to the lack of diversity it actually provides and though I do agree I think that they still do their job just outside of Ranked play. In the different fun modes or ARAMS you can switch them up and still have fun. The real thing I wish was address though is the actual insurmountable cost in which it takes to buy them. Most players never even bother to think about it because they buy the iconic base needed runes and never bother to buy any others but I am a bit of a completionist. I have been playing for 3+ years and have spent nearly all my IP toward runes. What has that left me with you ask? I still need over 200k IP to finish the runes. How did they ever figure diversity was even an option if the time it takes to collect all of them is well over 3 years? I don't know whats worse, the fact they are just now realizing diversity is impractical in a competitive point as far as runes and masteries or they still haven't even discussed the ridiculous cost.
