New "Challenges" Idea for League

I've been playing more League of Legends lately, and I noticed how hard is too try and get IP. I thought that there could be a little system created to help players who are more committed to league. There could be daily, weekly, or even monthly challenges. A daily challenge could be something like winning 2 game, getting 300 cs, or destroying 5 turrets. After the game you complete this challenge, maybe you could get a 50 point ip reward. With weekly it could be similar but maybe a little bit bigger challenges. Something like getting 25 dragons, or 15 barons. The daily ones could be rotated between a pool of general challenges. And same for weekly, just changing them at the end of the week. (or Tuesday when free champ rotation is) I just thought this would be a really cool idea for players who are trying to buy a new 6300 champ and runes to go with it.
