When folks say "The game doesn't teach you how to play!" this is what they mean. You should be explicitly trained on everything here by the game itself, but you're not and most have to either learn from guides or muddle through (often eating floor) to do so.
Yes, Game Designer, you do have to explicitly teach your users how to play your game and you have to gate content access behind that tutorial. Behavior proves it. Suck it up and do what needs to be done.
Yes, Game Designer, you do have to pick a standard and stick to it. All bad actions use this telegraph, good ones use that one, and that goes for sound effects too; don't let the players or anyone else use Danger Bongos for non-danger purposes.
Guides are an unfortunate reality, especially with online cooperative multiplayer games like MMOs, but they shouldn't and it's got to stop.
And since I missed this when I first made this post, I'll just add this video guide in here. This should be in-game if you play FF14.
