I have to admit that I got quite frustrated last night with Midas 3 after running it 15 times successfully with over 9 wipes, I know the mechanics like the back of my hand but I can't speak a lick of Japanese to communicate with my party. Google Translate didn't help in the slightest, luckily I occasionally play with a Japanese friend who can translate what I say so that helps.

If you're in an NA/EU data centre and see the someone is new message, ask if anyone doesn't know the fight, no response? Well it's safe to assume they've read or watched a guide, otherwise go ahead and call them out for not speaking up when you asked. Might be an unpopular opinion, but if someone asks if you know the mechanics and you don't but you don't say anything, you could potentially be a hindrance to the entire party. I understand not watching a video not to spoil the fight, but text explanations of mechanics can hardly be called "spoilers". If you consider them spoilers, run with your FC or create a PF group, don't go to DF if you're not willing to ask for and take advice.
