Dear Riot: I am concerned about keystone runes

With the Dev blog that was released today, we learned about the upcoming rune changes for the pre-season. I wanted to commend you on making runes free, and allowing them to be altered during champ select as I think that is the right direction to take the rune system.

However, I am dramatically concerned with the current ideas of keystone runes. You I believe that keystone runes will give us far, FAR too much power in our games if you put this change through. Berserk for example synergizing with Fervor would be incredibly unhealthy for marksman, while overhealing and prixie would be unhealthy for windspeakers supports (either having them themselves, or having an ally have it). I really hope that this is a change that you can revert as you are giving us too much free stats to work with in our rune pages.
