One of my minor gripes with FFXIV is the lack of elements that feel uniquely Final Fantasy, or well, unique in general. It feels too generic, and one thing contributing to that is the lack of elements unique to the Final Fantasy franchise. For one, the spell names.

Even back in the original FFXIV, spell names from the rest of the franchise were used. Fira, Firaga, Curaga, Thundaja, so on, so forth. Re-adding these would not be difficult at all, and add back a little bit of Final Fantasy charm to the game that in my opinion, is currently missing.
