I would add an extra furry race. Something like Hrothgar, but less bara. It would probably be the Burmecians. Rat people would be adorable, but unliike the Burmecians in IX, I would make them TINY. Somewhere between Lalafell and female Au'ra, but not more than half between. They would be a new small race, and it would be AMAZING. I'd tie them to Meracydia, and make it so that they were once part of a thriving secret city state civilization, but were wiped out recently, and have since migrated. That would be my lore excuse. >o<

Then one day we'd return, and get to explore the fallen tree city in Meracydia.
