With the new influx of mounts from Argus and the fact that all class mounts for the overall collection, it has become fairly easy for mount aficionados to push past 350, and by the end of the expansion it will no doubt be possible to reach 400 exclusively with mounts that are available in game (it might be theoretically possible already). I hope Blizzard will take note of this and release some new achievements in the near future.
What rewards would you like to see for these achievements? Unless they have something completely new in store for us, which would be really nice, here's my list of potential candidates:
1.
The original Warlords Chimera - this is an amazing model, very reminiscent of the scaly chimeras from Warcraft III. It's a real shame it hasn't made it into the game so far, and a unique and exotic reward for mount collectors would be a great way to add it in (unless they plan some future content where they will make more extensive use of it).
2. A dread Roc, in
Alliance and
Horde colors. This model uses the same skeleton as the dread ravens and skyscreamers, so it would work perfectly as a mount. Looks incredibly awesome as well - the only problem with using them for collector achievement rewards is, well... I'd like to see the other colors added in as well. That, and the fact that they are still missing saddles.
3.
An albino Mana Ray (although
the Teal is very cool as well), provided they fix the size and animation issues with them.
4. A storm Drake - potentially
Green for Horde (Forsaken-style) and
Blue for Alliance. Not the most inspired choice, but they are cool new models, and the other drake colors deserve to be in game besides the Valarj'ar.
5. An
Ivory or
Icy Cloud Serpent. Really nice models, should be in game, but then again we had a Cloud Serpent at 300, so they might not be the best choice.
6.
An Infernal recolor. They're cool and I'd like to see all three remaining ones in game, so I'd take one of them from a mount collecting achievements, but they might not be the best fit since they are ground mounts only.
7.
A toucan. Yes, I still want a toucan mount. Slap a colorful tribal saddle on a giant toucan and let it carry us with its little wings. It would be freaking amazing. Don't skimp on the size, either. Make it large enough that a troll can ride it without looking silly... don't spoil my dream!
