Hello,
Another quick suggestion that has come to mind, personalities that a player can equip in the vanity chest, this will then change idle animations, maybe moving animations etc. Purely cosmetic of course.
An example of this would maybe Gold Hoarder personality where the idle animation is your character inspecting gold or Hunters call personality would see your messing around with a fishing rod or a fish
And maybe the personalities come with an exclusive set of emotes like some of the costumes have these days
For some they are locked behind an achievement or maxing out the faction like you get the Merchant Personality after selling x amount of items or reaching merchant 75
Some others could be sold in the pirate emporium or attached to other costumes like Jack Sparrow, While idle could have him holding a rum bottle and swaying around and when you run it has a jack sparrow run animation.
Thanks for reading,
