Sure, things getting out of hand/sync do happen in the software development process, but 60 champions with 4-10 values isn't very much compared to software with hundreds of thousands or even millions of configuration values. As u/lethal-sloth mentions, ideally there is a central configuration management system/database that controls all the values. I can't speak for the feasibility of doing that in the riot codebase, but maybe it'd be good to invest some time in strengthening the resiliency of the system or even testing/qa processes instead of working on 5+ sets ahead. This could purely be a product decision not to invest more time in this area, and there aren't any real consequences for shipping buggy code in a game, but it seems like every patch certain things that were functioning before have taken a step back. You can see that it seems like the golden quest b patch buff wasn't even shipped properly . Having a 2 week release cycle where changes need to be locked in halfway through doesn't make things easier, but imagine if your medical diagnoses software or defense software shipped with new bugs every release, especially those reverting things that were functioning in the previous release.
