While yes it would be tons of work to create a new race. This isn’t a starting company that was funded by “Go fund me”. This is a multi million dollar company. They have resources and could put teams on creation. Its not like one guy would have to do everything. We can’t even have basic character customizations. The company is lazy and wants to spoon feed us slivers of content so they can say its a " feature" and make a big deal about it. Look at Velf DH just one race got one class.
The company is going to cut corners and do lazy practices because they want to save money. That’s what’s it’s always been about.
