Patchs are getting so unbalanced

The PBE is for testing for bugs. You put a few people from all over the world and every different rating onto a single server, where bronze players face challenger players and people routinely have 200+ ping and lag spikes, and you're never gonna get a good idea of balance changes that are being made. You are, however, going to find bugs that need to be fixed, such as a completely gamebreaking bug that I found once where an allied Spirit Guard Udyr pressed E and crashed all 10 players in the game. I reported it to Riot with a special PBE report ticket, the skin was removed for a few days while they fixed the bug, and everything came back just fine. If nobody else from that specific game had reported the bug, and if I hadn't, that bug may have shipped to live and had some hilarity ensue in some poor sap's ranked game, exactly like what happened in my game where the Udyr used his global 10-man crash button to crash everyone every time he was about to get killed. Meanwhile, because it crashed everyone, that's all his E was good for; that Udyr was completely unable to use his main engage ability for that entire game.
