How is BLM?

[Sylvain]

The reason why everyone says BLM is hard to master is because it requires planning and fight mastery to optimize. Looking at BLM at a beginner level, you think that you lack any kind of movement and will get destroyed by aoes or lose a lot of DPS to move.
But BLM actually has a lot of movement options. Procs(firestarter and thundercloud), xeno, tripcast and swiftcast which all allow instant cast spells.

So much so that I have to actively spend Xenos during ice phase otherwise I overwrite stacks. This is especially true on Diamond x(... all those wasted Xenos
