They are organizing in Classic Era and people are playing. I’m sure they’d love more.
Maybe if you didn’t activate your clone in Era and moved on to TBCC, consider giving Era another chance since it is not progressing further. If you are interested, get on it quickly as the unactivated clones in Era are going to be wiped.
Makes me think that Blizz is not only making room for the SoM characters but they are not interested in snapshotting/cloning. Perhaps they will come up with something different.
Maybe a seasonal server for TBC content!
