you cant stop it as blitz, both the knockup and the pull only work once trist is in the air moveing and ez like you said gets out of everything.
i literally cant do ANYTHING to an ezreal as
.. it it has NOTHING to do with my ability to land my skillshot.. it has to do with while every other laner besides him and trist atleast has to respect the pull. ezreal and trist can completly ignore that and walking blantantly in front of minons while csing and becuase the cooldowns pretty much match my cooldowns.. he can do it EVERY time my pull is off cooldown.
its a stupid gimmik that shouldn't exist. this skilsl are designed for mobility NOT for being immune to CC..
if they champ has a spellshield like morg or silver or even nocturn.. SURE thats DESIGNED to block my spell thats it INTENDED effect.
its not some mobility skill that just happened to have the effect of making him him immune to all CC during the process
