I love this post as someone who is new to MMOs and also not in level 50 yet. I would much rather do the work and get educated ahead of time, than be yelled at the entire time I'm trying to do the dungeon because I didn't know what I was doing. I, for one, will do the work I need to do before the dungeons so I don't feel like an idiot. This should be advice for EVERY instanced fight, not just the endgame content. (Tried running Qarn again to clean up a hunting log... That was fun...)

One more thought: When playing a regular Final Fantasy game, isn't it more fun to power level, explore content, and find hidden things before you get to bosses? If you just run straight to the end game without doing anything it's super annoying. Tried it the first time I played FF8, and hated the game. Second time I played, I did the work to get Squalls best weapon on disc 1, which gave me time to really learn the mechanics of the game, and it completely changed the experience. Just saying.
