One problem I have with this game.

I'm wondering if this is why people are required to read guides, because Final Fantasy XIV likes to change it's own rules a ton.
It would make things a ton easier if icons stayed consistent

I agree with this, there are some fights where it should be more visually obvious what needs to be done.

Like those positive and negative charge markers so you know they will attract or repel to the other tethered player.

Things should be distinct and easy to remember so it doesn't become like cramming for an exam trying to remember lots of abstract symbols meaning.
