Hi. Happy almost 10-year!
We're shipping some pretty big changes to Garen, Shaco, and Viktor this patch. Not big enough to be considered "rework"-level lists, these larger changelists are meant to excite the players of these champions, freshen up their kits, and lessen common pain points that have developed. We want to also make sure we're hitting the identities players expect of them and give them more viable and exciting playstyles that should appeal to current, past, and, hopefully, future players.
Other than that, we're keeping the scope of this one pretty small, as we move from focusing our work on Worlds-related preparations to finalizing changes and tuning for Preseason 2020.
