False, they made a blue post about this before the expansion launched. We're getting more wings on the 8th of December.
No thanks, they did that the last two expansions. The majority of the community believe endless grinds are toxic to the game. And it does bring about toxic behavior overall, there's a reason the game was at it's most successful for several expansions when there were limits on what you could do each week.
I'd be fine with this if there weren't power gains from it, but there are so again, no thanks. Toxic gameplay involved with endless grinds.
There are 2 mounts that work in the Maw, and from a lore perspective this makes complete sense. One is from a rare inside the Maw and the other is from reaching a milestone within Torghast.
