I was kind of disapointed when I knew that FFXIV didn't have the names with ra/ga/ja at the end.
It is also very strange when we see a boss basting Fire IV, with it being very different and wide AoE, when BLM Fire IV is single target.

I think that BLM's Fire IV should be Fire III, Fire II should be Fira, and Boss's Fire IV should be Firaja.

I mean, every other FF that I played was with ra/ga/ja to represent a different tier, They didn't need to change it.
