Knowing when to switch your main class?

Thanks for the great answer. To answer the question you raised, I find that I get frustrated by the fact that I'm not as mobile as the others. I try to mitigate the movement as much as I can but I can't really see myself improving on it. I find myself getting really stressed out when I mess something up because you lose a lot of dps as a BLM if that happens. I've also come to realize that planning ahead is not something I'm good at and to be honest I'm not finding it that much fun.....

It sounds like BRD might be more up your alley. TBH though every job has to plan out their CDs and other elements of their job if you wanna play well per the encounter, including BRD, so keep that in mind.
