Something may useful to you:

1, http://www.ffxivguild.com/ Please check all boss skills and fight mechanic before go in. Youtube sometimes not clear enough to understand it.

2, Use PF to find some serious players / FC / LS to form static party, Baha T5 + need practice over and over for normal players. Static party would help a lot.

3, Atma.................can do it by yourselves and no hard content.
