HOW TO FIX LEAGUE OF LEGENDS!?!

OK SO..i have seen so many players complain about this topic which is about how long it takes for late game to hit. There are people out there that love watching the lcs but they dont even bother watching for like the first 10min of the game because MOST of the time all there is to watch is people playing safe and killing minions untill they get their items to finally make decent plays and sieges. i honestly think if riot were to boost the exp rate and gold rate by a decent amount itll make league a more fast paced game and wont tilt players as much either because who wants to waste about 1 hour of their life trying hard and then end up losing? but if the games were to reach late game faster there wont be a need for so much tilt or mental stress because each game would start and end within about 15-20min max lol SO i think they should make it that players can reach lvl 18 and full build within 15min max. this will cause players to wanna play more because they can get in and out of a game within 10-15min and if they lose a match it wont hurt as much considering u wont have to waste another hour of game time hoping u dont get paired up with trolls ect. PLEASE LOOK INTO THIS AND TAKE THIS INTO CONSIDERATION :D
