The profile UI has been simplified a bit re-arranging where we used to see personal info about our characters. This is a look at the Profile’s Career Page — before and after.
The Profile page for each individual character has been also simplified drastically. Unless the current state is a placeholder, a lot of graphics have been trimmed out. Likely to enhance server stability, but that’s speculation on my part. This is how it looks on Diablo III vanilla and how it looks on Diablo III: Reaper of Souls.
