Reverting Quality of Life: Tank Stances

[Shurrikhan]

This isn't something exclusive to tanks; all jobs lose their persistent effects when level synching. Monks lose their fist buff, Astrologians lose their sect, summoners and scholars have to resummon. It's more of a problem with how persistent buffs are handled in level sync in ShB, and it's something that they probably should address sooner than later.

Then, let's fix that, too?

This is more easily said than done. I highly doubt this was a conscious change. It is probably due to a quirk in the code that even Square-Enix may not fully understand. It could actually be very difficult to fix.
