Well legion got me back I did quit during MoP and WoD.
Was legion as good as vanilla? No but I played till ToS mythic… So, it had my attention for a bit. It was ok not great but ok.
To me WoTLK was ok. TBC was good and vanilla was beyond brilliant made me a one game show. Couldn’t play another game only WoW. That in itself is a feat.
Then BFA played a few months and well never returned. Waiting on classic.
