A Super minion is stronger than Bard

In one game our bot lane inhibitor was down. While rest of the team was in other lane pushing, I took the responsibility of taking care of the super minion so I thought I could. I auto attack with meep then q then auto attack with meep then q omg I couldnt kill him. His health was going down slowly little by little. Its health regen was faster then my damage. I was litterally being push back. Then another super minion came by and they both push me back to the nexus turret. I had to message my teammate COME BACK I CANT DO THIS THEY ARE SO STRONG. So I had to ult the turret which gave them enough time to come back and kill the minions and save turret with 100 health. That was embarrassing.

That game was bad we had two auto lock Top and I had to bot with my jungler lee sin because we had no ADC
