Oh, I know. I've been a night elf fan and played through both MoP and BfA, after all.
I just want to believe things can improve. Being cynical all the time gets draining, so while I definitely agree with you, I will try to find something to be hopeful about. Like the fact that now that N'Zoth has been tossed in the trash like nothing, it's unlikely that they'll do so again, so I can't be utterly disappointed by that again. See?
