Yes, it is annoying.
Hmm…
I know what you’re talking about but I don’t know when exactly this changed because I haven’t really been actively playing Era the whole time. I do know that when SoM came out there were a bunch of bugs that occurred in Era and Blizzard took a long time to fix them. Maybe someone else knows? I did a bit of research but was only able to find a thread from July 2020 which is before TBCC so that wouldn’t count. Maybe there’s some relation though so I’ll share: Combat state persisting for far too long in PvP - WoW Classic / WoW Classic Bug Report - World of Warcraft Forums (blizzard.com)
