The boss mechanics in the game are sorely lacking. I'm fairly new, so I've only seen a few, mostly DH and the job battles, but with what I've participated in, and the videos I've seen, they do not impress.

I am willing to tolerate it for now, as I know the devs are trying to balance a lot of things at once. All new MMOs tend to go through these problems, and FFXIV is even worse off due to where it started from. I can only say wait it out and hope that things get better.
