I feel the only problem I’m having with said “grind” is the Skyscale one. Heck, I found the beetle and warclaw to be painless and easy going...
I personally would have preferred a little more grind for the normal mounts. I think we were given mounts a little too easily. The skyscale was kinda the perfect amount for earning them.
The Griffon/Beetle/Warclaw was pretty cool, but I like to feel like I've earned and gone through a story to get my stuff. It means a story can be told.
