Stop acting surprised that they got gutted this patch. It was intentional. They even said it on the patch notes. They're purposefully making these two problematic champions not-viable for pro play right before Worlds so it isn't dominated by these two champions.
They are going to buff them again for the patch after Worlds. They just need more large-scale work that the devs are likely saving for preseason. They couldn't fix their mistakes fast enough to keep them from ruining pro play, so they're gutting them now while they work on a long-term solution.
Give it time. They're gonna suck now, but the devs aren't satisfied with their current spot. This isn't where they will stay.
