What would you add / change to the FATE system?

I'd like if more of the FATE bosses had unique mechanics instead of just being a bigger, tankier version of an existing enemy in the zone.

That flan boss that showed up for the most recent Heavensturn event was a good example of how you can use an easy boss to help prepare people for tougher encounters by making the mechanics a bit more elaborate (It did desync'd cone AoEs that formed a full circle, as well attempting to knock you back into scattered circle AoEs), but not that punishing if you mess them up.
