The knock back plant

I think this plant should not exist because it rewards you if you are lucky enough to get the plant to exist when you need it and not only that but you can also troll your team by knocking them back into the enemy team and they just get gangbanged or knock back a garen into your sivir and he ults her and she is dead.... JUST DONT GIVE TROLLS MORE TOOLS THAT THEY CAN TROLL WITH PLEASE!
