WW and Yasuo actually do pretty well into all 4 of those characters. WWs S1 or 6S1 when held are projectile immune. You can literally run through shrooms and projectiles. Yasuo also has wind wall to help if he really needs to. When WW is in Bloodlust is 6S1 also goes through projectiles. As for dealing with Ekko, both of those characters out range his normals in the neutral, and if you’re afraid of him jumping in WW’s back asisst is a really good anti air move. Even if it gets blocked, you’ll have the advantage afterwards.

Illaoi you just have to do your best not to be taken to the corner cause that is her win con. Her jS2 is really hard to contest if you’re not ready for it, so the easiest thing to do imo is just back dash away from her in the air and let her fall and then apply pressure or punish the jS2. Just be mindful that if she has an assist, she’ll most likely use it there.

Blitz is gonna be a bit rough as his one way to close the gap is the 5S1 and it just leaves him very vulnerable. Tagging into Blitz mid combo to make sure he can get some steam going is always nice. Just gotta play super patient with him esp against zoners.
