Outside of Lore, I'm assuming they thought as in the western translations of some of the older games had numeric magic upgrades, the west would prefer it, but as the same time we've had more games with suffixes than numbers so its not like its a common trend
if that was the case then they should guve us a option 2 have either numbers or the names like fira
also higher cureage is Cureja so that is stupid if they put that in a book lol
