please God just call it port

[Iscah]

Also while on the topic of localisation goofs, can we talk about how Chaos's longitudinal and latitudinal attacks are swappeed?

Longitude should be sideways and latitude should be upwards and downwards. Not a big deal in NM with the AoE markers but in Savage it sucks having to process that they're swapped.

I can see that it can be ambiguous, but it makes more sense as they've arranged it in the game.

Lateral basically means "to the side". It's not even an obscure word like 'larboard'. (See: 'lateral thinking', approaching the problem indirectly; also the many phrases listed on Wikipedia's disambiguation page)

There's all kinds of archaic words used in FFXIV. It's a stylistic choice.

EX: eikon instead of icon

[Berteaux_Braumegain]

I'm sure someone has already mentioned this, but this is an especially weird name convention for an attack considering that Temple of the Fist has a boss who also uses nautical directions for attacks. And his side attack is called "Port and Star".
