Wave clear????

So, I'm a jg main who recently took up ADC as secondary and soon primary hopefully. For some reason, I always have the best KDA, pressure, and wins (fun) on MF but my CS is lower than xayah, JInx, etc. by 2 CS a minute. Is this just because she has no AOE or are you supposed to use her W to push waves harder/quicker? I feel like my pushing power is weaker overall. Thanks for any insight!
