As suggested start up a PF practise group if you really do just want to practise, I've done it myself a few times to learn the fight (cough I hate you moogle ex)
The problem with the "go watch the video" mentality is that usually the in depth ones are from a single point of view, like from a healer or a ranged DPS, which does nothing for those on melee, also some and I won't name names are over half hour long and boring as hell with a guy with the most annoying voice since peewee Herman which is an instant turn off
If I want to learn the fight though i do it via PF and not expect a carry in DF
