Thanks for the suggestion! We've sent it over to the dev. team for consideration! In the meantime, just want to suggest that you can toggle the auto-face target option with text commands (instead of using the menu) which may be faster for now.
When switching to a healer, /autofacetarget off and if switching back to a tank/DPS, /autofacetarget on.
Either way, we've passed along your idea!
While it may be a little different from your suggestion, the dev. team is checking to see whether it would be possible to alert the players when they are nearing the border of the FATE area.
We have been receiving this request for some time now globally. The dev. team is checking if it would be possible to add an option to toggle the battle music on and off.
