@Riot Time-gating?
There is a major issue with time-gating on new players. This is a much bigger issues since autofill was added. Due to the fact that you can wind up stuck in any role from autofill, you need to have runes for every role to play in ranked without a chance of winding up with runes that don't work. The amount of runes you are going to need is roughly 40,000 IP. If you play an hour a day, that is roughly 4 months. There is additional gating that stops new players from playing certain champions. If you want to play a champion like Corki, you probably need mixed penetration runes. Between the 820 marks, and 2050 quints, it will cost you 13,530 IP for the runes for a mixed champion. If you're a new player you should probably just avoid Corki all together, as he would cost you about a month of IP. This is forgetting any chance that players might choose to buy rune pages or champions with IP.
Riot seems to want people to play a variety of roles and champions so that autofill works. Well it isn't working for anyone who hasn't played half a year for runes. There isn't any need to keep new players doing bad because they lack the base stats of everyone else long after hitting ranked.
