Achievements In League of Legends

So I have had this idea for awhile.

The only way of gaining IP is through winning/losing games, why not create another way of gaining IP? I think that Riot should introduce Achievements into the game in order to motivate more people to play different champions, learn new roles, and ultimately find another concept to enjoy the game.

Here's my idea: Each champion carries around 15-30 achievements. Every achievement is obviously going to be harder than others so the ones that are harder are going to be rewarded with higher IP. Now I don't mean that if you achieve the hardest achievement that you'll be rewarded with 500LP, but more on the lines of say 50-200LP. The easier achievements can be rewarded 5-25LP. Riot will keep track of your achievements through your account and eventually you'll also be able to unlock certain avatars based off of the achievements you have completed. Another addition is to add achievements based off of the map you are playing on.

For example:

• "Achieve 5 Dragons in under 40 minutes" (Reward 150LP) - Summoner's Rift
• "Stun 3 enemies at the same time with Event Horizon" (Reward 20LP) - Veigar
• "Achieve a Triple Kill with Requiem" (Reward 125LP) - Karthus
• "Regenerate more than 5,000 Health in one game with Sadism" (Reward 90LP) - Dr. Mundo
• "Kill Vilemaw more than 3 times in one 3v3 Game" (Reward 100LP) - Twisted Treeline

This achievement system copies the idea of Team Fortress 2 where each class has different achievements based off of the character's assets. But why not make it more enjoyable with the addition of LP to encourage players to try new things. Oh, and if you say that this can be exploited then perhaps make achievements only obtainable through Normals 5v5 or 3v3 Blind/Draft/Ranked Pick.
