Need the equivalent of a 3-pointer in basketball

I've been in 4/4 landslide lopsided games tonight. In basketball the game got stale because there was no way a team could come back in the final minutes when a lead had been built up. So they added a 3-point line. I propose adding the 3-pointer to a special queue where there is some come from behind mechanism. Maybe the loosing team gets higher buffs from the dragon and baron to reward them even as they are behind and pull an unlikely epic mob kill. Maybe if the loosing team gets a double, triple, quadra or even pentakill they get higher and higher buffs which allow them to come from behind - an extreme rarity in todays games which are sometimes over before I even get out of the jungle. Sometimes I just have to wait around till the 20 minute mark and even then sometimes people don't always /surrender driving me further insane.

Don't just blindly reward them but reward them for exhibiting skills like teamwork. If a team is good together but have fallen behind early they should be able to come back, not just run around getting killed till the next game.
