This.
Back then Guild Wars, SWTOR, Aion, Wildstar etc broke their teeth because WoW was still such a popular and GOOD game. Not anymore (imo). That stopped at the end of Legion. I guess Sargeras stabbing Azeroth with his sword was more than a symbol for the game. After BFA Blizz had to deliver for SL. They did not.
I moved to FF14 for now and there is not much from WoW i am missing so far tbh. Beside the nostalgia of the great king of the MMOs it once was.
For me WoW has never been in such a weak position in its history. I hope competition will make them move away from e-sports and bring back the RPG in MMORPG for wow.
