Mini Trahearne, he's my favorite character and I really wanted a mini of him since a month or so after launch, so I was happy when one was finally released 5 years later. He stays permanently equipped on a couple of my characters now. For minis not based on named npcs, my faves are probably the mini mounts (not the shrunk down 2k gem models, but the series that look like babies of their species), especially the raptor hatchlings.
