"please design something fair to deal with."
The champs have pretty clear weaknesses.
Yasuo:
-Yes, he get's a passive shield, but it's pretty small and doesn't last that long. You can bait it out or pop it like a Malzahar shield by just going for a quick auto or spell.
-Windwall is on a LONG cooldown
-He relies on his high mobility to dodge and position, and his mobility is directly dependent on having targets to dash through. Try to not fight him in a minion wave.
-His ult roots him in place for a short duration, unless he somehow got your whole team (which is more your team's fault for positioning poorly) then someone should be able to take this opportunity to lock him down
-After he uses tornado there's a decent period of time before he can use it again as he has to charge more Q's, you can usually try to fight him in this window
**Thresh:
**
-His cooldowns are LONG. If he misses a hook he has to wait 20 / 18 / 16 / 14 / 12 second (without CDR) before trying again. This is his primary engage to help him get on targets.
-Lantern is an amazing ability used properly, but it's also on a 22 / 20.5 / 19 / 17.5 / 16 second cooldown.
-Flay's cooldown is a flat 9 seconds, which is still pretty long
-Plus, usually when Thresh is in, he's in, meaning if he engages a bad fight he's probably going to die. A lot like Leona, Players have to be careful and make good choices on when to fight.
Zoe:
-Her damage is pretty reliant on her landing both of her primary skillshots, if you can dodge or somehow outplay the bubble she does significantly less
-She has no good escapes. This is a big one. Zoe may be REALLLLY annoying from the range she likes to attack from, but she is actually really immobile up close. Her ult tells you exactly she will land after the ability ends, and can only position her back to where she started. As long as you don't carelessly blow summoners around her, she has a hard time getting out of good engages.
Don't get me wrong, I hate these champions too, especially Zoe, but it doesn't mean that they're unbalanced or 'unfair to play against'.
