RIOT can u stop?

Hi. After I saw how good is syndra in worlds and I went for a month of playing her to be good at her and when I finished and started to carry some games they nerfed her ult. Really?? She was so balanced what is the point of picking a slow squishy 0escape champion if she dont have enough burst to kill someone 1vs1. They buffed kata which was already good and balanced but now... her ult was already good. Buff garen while he was fine?? He was ok and have nice tank and useful abilities. What about graves totally useless champ which I was maining but I relized be is useless I heard he got 6 nerfs before and 0 buffs even after he gets fed he is still useless so he needs buff. I dont know about the new jungle I tried Vi abd she is fine abd balabced champ. Camile the new OP champ which u cant catch bcz he has a very OP ult and a nice escape I tried ganking him few times but he escape ez. Heim? He is totally forgotten but he does so much dmg even before the nerf of syndra I focus him and kill him but his turrets kill me and he has ability which take about 40% of my hp and late game 75% what is that?? I agree with vayne nerf its fine.

Finally I love the game and I hope it gets better I know I must stoo complaining but there are true things that must be complained about they must think about what will happen after and update not just make updates.
