New level up system

Hey guys! I was excited about the new level up system. But now I'm dissapointed. I don't like it at all. You need 2 play like 10 to 15 games to level up and I'm sorry but I want to save money for champs I want the new system doesn't allow me to do that fast like the old one. From 10-15 games with the old system I would afford a 3150 BE champ. Now it's so hard to aford it. Thoughts about this topic? I really hope that Riot will change this.
