This update makes a big change in the transmog system: all drops found will now be added to an account’s collection, not just the ones equippable by the current character. A use case for the reputation and achievement changes is that they will save hours on obtaining the Legion druid forms (although they’ve said old reps aren’t coming right away).

We don’t have a lot of specific details yet, but a lot of it appears to be quality-of-life changes. There will be an account-wide reagent bank for professions; just that alone is a massive change. Unified flight paths is a QoL change that will also save people thousands of gold, designating “favorite” characters gets around realm swapping, etc.

I have multiple friends that are over the moon about this announcement. People love their alts.
