nerf or make yummi targetable during attachment

just laned against a bot lane duo with yummi and ezreal, legit just contracted all types of terminal cancer. i was naut, caught her so many times, but all she would do is attach to the ezreal and ezreal would e away and yummi e just heals half their health back. i tried to focus the adc, but he was allways too far away since yummi was just in front of everything just zoning us.literally impossible to lane, so she would stand in our faces and poke us hard without any risk nor punishment. what im asking is to either nerf her attachment range or just remove the untargetable status of it. its literally free zhonyas and ungankable lane with yummi and ezreal. they shoved us balls deep and everytime we go in they just easily run away or yummi just attaches to somebody else.
