Watching content before actually doing it?

I think watching video before boss fights is OK.

Why? Lets imagine, inexperienced player joins the fight. Lets suppose, that he is silent about it, and fight just starts. If a player passed fight from first try, all is good, but I can't imagine how player can avoid for example aoe explosions in ifrit (when everybody should be under him, and rest of field explodes) or bombs on titan (it is not obvious that these rocky things are bombs and what to do with them) for first try.

So, first wipe is likely to occur. It's fine, things happen. Then player asks to explain fight (if not, other wipe likely to occur). So instead of listening that explanation words (and better - see some visual illustrations) on video he asks players to type all that explanations right now in chat. Why make people type these tactics, instead of watching something, that is made clearer and in more detail?
