What if Poppy's W was changed to stop only the first enemy dash?
Poppy's team fighting is one of the best because of how easy it to peel and initiate simultaneously with her W. Most champions only have one dash/gap closer to begin with so only blocking one dash per champion only really creates the illusion of counter play against it. Changing it so that it just blocks the first dash means Poppy can't just activate W and do whatever she wants while the enemy is forced to retreat since any attempt at counter initiating is almost always nullified by her W. The change would create more depth to using her W and her counter play since an enemy champion can sacrifice their dash so a more vital champion can use theirs uninterrupted.
Just my 2 cents.
