Lots of proactive updates for gameplay, but if you address low level play...
For the sake of electric humanity,
ELIMINATE LOW LEVEL RUNES AND ALL IRRELEVANT RUNES.
It's an obvious resource trap to encourage new players to IP boost repeatedly when misguided.
You offer so many "newbie trap" runes, and not only are they worthless and misguiding, but they COST MORE than the meta ones that WORK!
New players should be trying out champions, and not be limited and roped into buying crap runes that destroy any chance they have at winning their lane.
Bla bla bla, you know what you are doing. Get people on the right path, eliminate your messy early game. Leveling one to thirty is also basically meaningless torture the way your system is set up.
