"Hi everyone,

The detailed patch previews, looking to adjust into discussion off the 1st post (eg. y'day that just contains the list of content being changed) and then designers (and myself) will be following up on things that are being datamined to offer corrections, etc." - https://twitter.com/RiotPhroxzon/status/1630758953557852161

Editor note - With this, after this post I will probably just contain these to the monday Patch Preview posts, and have that act as a living log as designers come in to remark on changes. Keeps things more self-contained and less spammy. As such, if I've missed anything, now and in the future feel free to point it out or even DM me since I usually mute comments on these posts, but read through them for my own interest.
