Regarding new champions
Just my 2 cents.
Everytime RIOT releases a new champion it makes me want to not play League for at least 1 week. I'm sick of people playing for the first time a new champion after 1 hour of its release in ranked games. RIOT needs to understand that only a small part of the community has a PBE account that allows it to try new champions. That being said, i would suggest to release a new champion and make it playable only for normal games for at least 1 week so people can learn it without ruining the game to people who are actually trying hard just to climb a little bit. It's frustrating.
Don't tell me we can ban the new champion because 99% of the times the X guy pre picks it and straight ints if you ban "his" champion.
