Seems relevant:
The question is whether this reduced batching window and seal persistence (the seal is not specified; the wording allows for ALL seals to be twisted) is specifically for Classic or whether these changes continue into TBC.
If seals are meant to work this way in TBC, as well, then it’s definitely a bug. I can’t imagine they added seal twisting to Classic but not TBC where seal twisting was actually more prevalent and impactful.
