Gameplay

So I was playing a game as poppy and Warwick comes to gank I'm low and run I'm almost under my tower. Knowing he's about to dash I activate W then he dashes and I die. The w didn't stop warwicks dash. Idk if it does it with his ult but please fix this. Warwick shouldn't be allowed to dash through poppy w he's already strong enough. It's frustrating when abilities don't work the way they should. Thanks
