Would it be possible to buff those champions after worlds?
I would like to enjoy playing 
again when he is reasonable in solo Q now that there aren't any major tournaments left before preseason so it won't affect the viewers as much as it does when they are played during LCS.
Kalista is obnoxious when strong, when she is weak, the Kalista player will go afk after 6-7 minutes, because he/she is 0/4 or something... Ryze - never was problem in soloQ. Azir - the shurima shuffle is too good - 1 man wombo-combos are generally not liked in the game - they make for good youtube clips and miserable gameplay for the enemy team - the game is not PvE. His laning is not oppressive compared to his previous version. Mediocre to bad champ, if you don't play him often.
No, because they'd still be broken at that tier for the rest of the year.
It's not like LCS players only play during LCS. They play during the entire year.
Kalista makes everybody in high elo want to eat glass, and Azir when good just outshines everything else. Ryze is actually decent too, but his skill ceiling + easily fuckupable ulti makes his winrate extremely low despite being popular.
There's no way to find a middle ground for these unless you rework them, and they failed once with azir and a huge number of times with ryze.
