Here's a saucy one...

Viera should never have been added, not because of the quality of the implementation, but because they got butchered in the transition, their less appealing Leporine features got erased, such as their claws and their 3-toed digitigrade feet, and a frustrating amount of people don't care about Viera being Viera, they want Viera to be generic animal person but rabbit, and keep asking for things that would make Viera stand out even less like adding rabbit tails. Hrothgar can stay idgaf about them, and while based on previous FF races, they are still largely original, so there is nothing to ruin.
