From what I can see there aren't even that many guides on 3.2 yet. Most videos I've seen on Sephirot for example are people recording their EX clears with no explanation about what's going on and that's not abundantly helpful.

I, as a mediocre to poor player where this game is concerned, try to watch or read guides to reduce my own margin of error but there is no learning experience like just trying an encounter. People will mess up their first time, usually, but once they get messing up out of their system they can get the mechanics down well.

Try to brush off the people who rage.

There are undoubtedly lazy players who do put minimal effort into learning anything but there are players new to content too and I think veterans forget at times what the biggest and most important step is in any learning process: Fail faster.
