Riot can you give games more ip?

I think the ip that riot games gives for games if vary little especially when you have games that extend to 30+ minutes like we need a increased ip gain normally games only give you like 250+ ip after daily ip rewards? But some games you only get like 220+ ip for a 50+ minute long game. Riot needs to increase the ip more depending how long the game takes place or just a overall increase for each game over 30+ minutes. The reason why im asking this is because runes cost like 820-2025 ip for the tier 3 versions and champions cost around 6300 to 4800. Maybe a 10 ip gain for each 5 minutes after the 30 minutes mark. I dont know just my opinion but a little increase of ip gain would be nice.

Math Base ip 150-175 (Estimate) Ip bonus activated after the 30+ minute mark Ip bonus base 10-15 ip per 5 minutes Max bonus ip gain ends @60 minutes mark (When the game is 60+ minutes the bonus expires) 30 minutes Divided by 5 minutes = 6 times 10 IP = 60 ip gain Base ip + bonus ip 175+60=235 IP (Estimate) 150+60=210 IP (Estimate) Base ip + Bonus + Win of the Day 175 + 60 + 200 = 435 IP (Estimate)

Values are just estimates they can increase or decrease IF you think this is just plain broken i will scrap the idea but it is just a idea overall.
