Last part of that entry:
Class and Covenant Balance
Tuning has been underway over the past couple of weeks, but much work remains. Our initial tuning efforts have focused on Covenant class abilities that were outliers on either end of the spectrum, including some substantial redesigns where necessary. The coming weeks will see continued iteration on these abilities, as well as the soulbinds that complement them. Balance in this area means pursuing a mix of offsetting strengths and weaknesses rather than identical capabilities, and our goal in this process is that every class/covenant combination should have something to commend it.
Alongside these specific areas of focus, we are all using this time to tune various endgame rewards, fix bugs (thousands of which continue to come from the in-game Bug Report tool - thank you!), and add the finishing touches that will hopefully make your journey into Shadowlands a magical one when the time comes.
