You have been for at least as long as me there. so i will just assume you haven't been asking for the Worgen/Goblin model updates or paying attention to that.
The first time they said that was back in WoD. "They're being worked on" would be a fine statement if that was the first time they used it, and if it wasn't followed by "but won't be ready for Battle For Azeroth", Meaning they are being worked on for about FIVE YEARS, and still wont be ready for the whole next expansion. so you can put another year here.
I Know some people that works with 3D, and i'm 120% sure that the only reason they wouldn't be able to deliver the model in like 3 months or something is because they are working on something else.
Just check how many new creatures we have on Battle for Azeroth, all animated and in high quality models.
When i say that i would upvote the "Lying to Us" is because blizzard never said "we are not working on it" even when they are not. Check Quivers for an example, or any other model bug that its there since the start of legion(Vengeance Metamorphosis animations are buggy as hell when using some skills like spirit bomb). It is not a simple joke the "Soon Trademark" for Blizzard announcements. They do Lie to us in a fashion way.
I'm not sayin we should come to Blizzard with Torches and burn someone. i'm just disappointed that we are gettin 6 races, and more throught the expansion and Worgens will still look like Shit, even tho Greymane showed alot of Worgen potential on the cinematic.
