I Hate Playing With a Yuumi as ADC.

My ADC experience with a Yuumi support basically goes something like this:

• Start laning phase, 1v2
• Eventually get hard focused in bot by enemy jungler and die
• Repeat 5x
• I end up like 3 levels behind my laner
• Yuumi outdamages me cuz they attached to the W-keying top laner the rest of the game while I'm stuck farming to catch back up

What am I missing? Is there an entirely different playstyle that I have to learn? My games just feel funner when it's literally any other support.
