Would you rather they do huge content drops as per normal? Personally I like getting less but more often so I constantly have something new, than get everything all at once and being overwhelmed.
When it comes to the class thing, they mentioned this like almost a year ago, but now you’re mad? I give you credit for playing a gnome mage, which could be argued is firmly rooted in cannon. But for me who played WCII and WCIII when they were current, we already had a number of race/classes that were anti-cannon the moment WoW shipped in 2004.
Added onto that is the BC draeni retcon; which makes everything they did previous, have done since, or have stated they plan to do, look insignificant. (Well minus Shadowlands, but that is differnt. There is new coke, and then there is crystal pepsi.) If you want to stamp your feet about lore you should start there.
