Black magic...kinda sucks

[Rongway]

....So yet again you are either skipping over the point, or ignoring it.

I understood you just fine. You're ignoring our point. Ironically, even after acknowledging that we're right:

The core of the BLM is rewarding you to standing your ground and keeping a good momentum going, and while you can define this as being 'a turret' it still doesn't mean you shouldn't be able to move when needed without fearing your DPS is going to slam into a brick wall.

And as we've explained repeatedly,

Jumping back to leylines / teleporting to other party members. And of course triple cast / swiftcast for casting on the move.

Aetherial Manipulation lets you teleport to a friend every ten seconds. Between The Lines lets you teleport back to your Ley Lines whenever you want. Thundercloud and Firestarter reduce your cast times to 0s and can be forced to proc. Between Sharpcast, Swiftcast, and Triplecast, you are guaranteed five instant spells per minute. This adds up to about 20% of your time in combat.

BLM is about moving as little as we can, we only need to dodge AoEs which can be easily done with 1 GCD, therefore swiftcast / firestarter proc and thunder proc is more than enough for that.

You should just accept this other point and move on:

It's your responsibility to make sure that [mobility-increasing cooldown usage] lines up with the times you need to move.

If you don't want this responsibility, play a different job.

Sounds more like you don't enjoy playing this type of job and that's fine, not everyone will like every job.
