I tried switching my main after SMN got the shaft over the past few patches. I thoroughly enjoyed the other jobs I played (BLM and NIN) even to the point where I went halfway through a Novus upgrade on BLM and was saving alexandrite to go full on with my NIN novus weapon. In the end though, I found myself still being drawn back to playing SMN, and now I'm 6 alexandrite away from finish the SMN novus. What it really boils down to is this: play what you enjoy. I play on PS4 so I can't parse my DPS unless someone else is doing it for me, but I know this: I kick a$$ in all the content that I'm familiar with (can farm everything up to T9), I stay alive, help meet DPS checks, raise dead players when healers are busy, and keep virus and E4E up as much as possible, and I have fun doing it.
