Unnecessary nerfs
Stop nerf'ing champions instead of nerf'ing the things breaking them in the first place. You're not fixing anything with these band aid fixes. If champions are still broken after you "toned them down" then maybe the champion isn't the issue riot, maybe it's the broken items you constantly seem to avoid talking about that are broken.
Guinsoo's rageblade and devourer seem to be the biggest offenders yet I haven't seen a word from you about this. You've nerf'd shyvana, udyr, and now you're gonna nerf yi yet both udyr and shyvana are doing just fine despite the nerfs.
Bruisers and tanks building full tank yet still shitting damage out of their ass, it certainly isn't the items that are breaking them though it's just their toxic kit right???
I'll agree that some champions are straight up broken due to their kit being so loaded but from what I've seen the majority of balance issues seem to be due to items being unbalanced and favoring certain champions more than others.
Tl;dr stop beating around the bush, stop turning a blind eye to this, fix your game riot.
