Rek'sai buffs?

Shouldn't rek'sai 's W knock-up aoe be a bit bigger?? since the melee range changes in many champions there are a few (e.g zac) who can auto-attack her while she is unable to reach him say if she needs to knock him up to escape. plus with all the item changes could AD rek'sai see some love? she wasnt made to be a kiteable tank, she is a killer but if i go ad i get blown up, if i go tank i do negligible damage and cant kill even a squishy. thoughts?
