I'm personally quite happy with the change.
I wasn't expecting BLM rotation to change much as it was, imo, good.
I really enjoyed BLM in the latest patch, ShB just adresses the few issues and frustration it had.

We now have a proper aoe rotation
We have a finisher (altough 3min on convert is quite overkill imo...) and for one I like how it looks. (the animation may be a bit too swift perhaps...)
Xenoglossy with the AF duration increase litterally solve the few remaining movement issue we had and the stackavle foul is both a blessing for foul management. I mean, I was already sometime squeezing 2 foul within 1 TA, with that change I'll probably be able to squeeze 3 of them ^^

Some traits are clearly filler such as 30s Sharpcast and 15% enochian.

I definitely think BLM core game play is now set in stone and beside few new quirck I would not expect any new mechanic to be added to the job for a very long time.

(perhaps improvement the thunder / thundercloud mechanic)
