Yuumi should take a portion of damage from enemies if she's attached to an ally

This may sound dumb but I always thought it was just not fair for her to sit on her allies and provide supportive duties while remaining at full health. Often times in game the best play is to focus the support but that's not possible with yuumi. Yes I understand she's squishy but lots of yuumis don't even run flash because when the ad dies they W onto the next ally. I think she should take a portion of damage if the person she's attached to gets attacked.
