Do BLM really have more tools tho?
Thundercloud procs are RNG ( I am aware of Sharpcast ), and holding back Triplecast for mobility does hurt your dps altho that's sort of a trade-off that's worth it if you know what you're doing but that's also where skill and knowledge of fights come into play.
Then you have Xenoglossy and the teleport only works against specific mechanics.

I really don't think that equates to more tools over 20s no positional req in total which is a long time if you actually save them for when necessary ( 38s for Monk with Riddle of Earth ).
Not to mention that you can still hit even if you do miss your positional it's still better than not attacking at all.
BLM also kinda just needs the tools because they have Enochian to keep up that very easily falls off especially if you have to move at the wrong time.
