Funny new champ / ability mechanic

Hey I'm Lord Spanky, I've played League of Legends for awhile, on various accounts, and I'va always been in love with this game. Recently I've noticed that more and more of your champions are getting more interractions with the map itself (Especially illaoi) Most people I talk to are not exactly fans of this, but I am. I like the concept of traps like teemo shrooms, and shacos, but there aren't any really good invisible ones with hard crowd control or other cool things like that. One of my friends was talking to me about how he thought the coolest mechanic in the game was a singed fling, and an idea popped into my head! What about a trap that flung you, like a catapult! You could chain a few in a row to scare junglers from entering your lane, or making funny plays in teamfights. Perhaps when a champion with health above a certain threshhold stepped on the trap, the point of impact could become a knock-up instead. I know that this trap would have kind of weird synergy with any kit, but that's really what riot games does, gets a cool mechanic then makes an awesome champion rotating around it! I was also thinking that when someone springs the trap it persists for a duration in which friendly minions will hop into it to damage turrets and friendly champions can step on it to escape or engage. In a way it works like a magical journey without walls :P Thanks for reading this and I really hope you put something cool like this into your game, Cheers.
