Praise the Emperor, we’re getting a balance update for 40k with a promise of regular updates to come!
See the updates here.
An active effort, on a predictable timetable, to keep the game as balanced as it can be is a great move on GW’s part and one we have wanted to see for, well, ever. Keeping the meta dynamic and striving for balance is a boon to any game and while it will never be perfect (not even Chess is perfectly balanced) it is a step in the right direction. Bravo GWs, hopefully we continue to see this type of commitment to quality.
