If you want to look at multiple languages all at once. For example, if you're coming up with the name of a job class or anything named (weapon, town, character), but you're struggling for a good word and want to consult other languages, you can look at all of the different languages simultaneously. If you just used Google Translate for this, you would have to run individual queries for each language.
Another use case is if you do a lot of one-off translations for specific languages. You can fix the localization for your target languages without running individual queries.
There are other use cases so users can copy the formulas I used and repurpose them for their needs.
