Blizzard is lazy when it comes to certain aspects of the game. The one I care about is the introduction of new mounts. I liked the triceratops mount. I thought it was nice addition. But now they have fallen in the slump of rehashing mounts that are already in the game. Example The armored dragonhawk for mount collector's. This is even worse than the 150 achieve reward that was the ugly kite. The new pegasus mounts while nice are just another invincible and sparkly pony lookalikes.
Now I was talking to a couple of friends and discussing how Blizzard could remain lazy while at the same time generating "new" mounts. Lets take the core hound as an example. It's already in the game so they don't have to design a new model just make the race models adjust to it. I think this will make a lot of people including myself happy. Azeroth is full of creatures that could be transformed into mounts and do not require much work to make races fit on them. And Blizzard doesn't have to put any effort into miscellaneous content like mounts.
