Earning IP

Earning IP is way too hard.To get a 6300 champ you need 6300 ip.And if you win around 100 ip per game that's 60 games or more!If every game is around 30mins thats 1800+ minutes spend just for a stupid champion!I main Yasuo , Zed , Lissandra , Kha'Zix .Thats 7200+minutes collecting IP just to be able to play 4 stupid champions!That is 180 hours!Its funny stupid!And don't forget the runes!Since season6 edned and runes got a few changes I thought I would finally update my rune page( it was the same since season4).And guess what... it took me 3000 f*ing IP to buy 9 lethality runes.And quints cost 2000+ ip.What?Didn't runes get reworked a year ago?If so the rework did not improve anything. In the lower levels I remember I was quite frustrated with how little IP I earned and I could hardly buy champions.And now I still am.I think it would be best if champions cost 1350ip and only some newer would cost 3150.NO MORE!Because otherwise its just annoying to grind IP to buy a champ.And runes should be much cheaper. Riot please do something about this!
