More LP gain for longer game wins please

The fact that a game win vs these: 5 afks, ff at 15, complete shitstomp and enemy team is inting is treated the same as a WIN in an all out war for an hour vs bullshit like full build vayne, xin, raka, ori, jarvan who get baron twice and elder once ( plat 4 elo LUL ) is, in my opinion, not right. Something like for every 10 minutes past 30 min, you gain +2-3 lp. (Or if the enemy team has a vayne who hits full build (shiv + ie XDDD) with a raka pocketing her 24/7 and they lose, just decrease them by a few divisions. Personal opinion tho [slayer-jinx-wink] )
