People who ask for buff in some nerfed champs need to realize something!!
So people ask for KHA buffs..Hmmm do you people remember KHA? yeah he was broken riot try to nerf him in 10 thousand different ways and he was always Broken no matter how much riot try to balance him so the SOLUTION was to nerf his base damage so there is a reason why kha is "weak" he is not "weak" he is a victim to his overload kit because if riot make the smallest buff KHA would dominate again!
Same goes with kayle!! Do you remember? same problem problematic kit that with the smallest buff she would be broken again!!!
Remeber yorick? god disgusting lane bully so disgusting that people actually STOP playing the game till this champion gets some nerfs (People from OLD GD would remember the post and what i am talking about) so you want this champ to be buffed again? no he is again a victim to his problematic kit!!
Now people ask for Yasuo buffs...WAIT WHAT? do you people forget the 100% ban ratio yasuo? no 99 no 90 but 100% BAN RATIO FOR 1.5 MONTHS yasuo broke all the records in win ratio and ban ratio again he is a victim of his problematic kit so again if he would be buffed he would be broken again!!
So people need to realize that some champs need to stay "weak" in order to not dominate the game and to not create a disgusting/boring/toxic gameplay!!!
