Some just random suggestions:
- Fav Icon
- Remove Post Count or at least on default thread views.
- Auto Merge Double posts or have some sort of rule. As time goes on people will abuse this even more so in the crazy faction section.
- Remove Most Messages, Most Likes, Most Points from Members page. It's already shown to be highly abused from what I seen and really does not add any value to the forums besides potential spammers.
- Fix a Theme coloring bug when clicking your name at the top right:
- Add Rules to a global sticky on just it's own URL at the top of the forums.
- Disable Signatures or Highly Limit them. Honestly their being abused to crap outside of images with Large text, bigger links and it never ends.
- 2018 Xenforo copyright? Maybe time for updating for security reasons
