I'm pretty sure they have been addressing these errors on the support portal. You can submit a ticket with these issues and look at the issues that have already been addressed. https://support.pso2.com/hc/en-us
I don't see any similar tickets and none of the known issues list anything similar. Are you certain about that, and that they're simply not displaying the translation mistakes they've made as known/resolved issues?
I am not sure they post everything on there, only the things that cause confusion like these: https://support.pso2.com/hc/en-us/sections/360008377533-Item-Related
It is best to bring up what you come across in a ticket so it can be noticed and submitted by the front line team. Submitting it on the forum and waiting for a GM to reply can be a lengthy process in most cases, but you didn't do anything wrong for posting it here.
Ah, thank you! I see your point; I'll throw each issue into a ticket and hopefully it'll be addressed soon. They're not glaring bugs per se; just minor annoyances. Easy things to miss.
There are definitely some things that could use an editing pass, but they can't do anything about them unless they are submitted as a ticket to support. Also, your last reprted item about Techter is not wrong. They already mentioned about how the name of the class is Techter, it was just the fan translation that called it Techer.
Oh, I did not know that. Well, thank you for the clarification/reminder!
