Whilst I have dabbled in Ex content, I don't tend to so much.

In my case, I've watched guides. Repeatedly. Sadly, I've found that I can neither remember the guide very well (if at all) nor perform in the manner the player(s) in the guide did. Even when I get something right my reaction time is often slow enough that I still get hit.

I don't tend to think about doing them so much anymore as a result. Not just because of my poor performance in such content, but also because the majority of PF listings say "watch a guide", "know the fight" or simply "Hector". And one first-hand experience of someone in an instance saying "didn't watch a guide?"

No point in someone like me queueing for those.
