Guar Racing!

Teargrants

Now that we will have guar, I believe I can speak for all of us when I say, WE DEMAND GAUR RACING!

In the meantime, my guild will set up makeshift guar races, please pm @KirinBlaze in game for details.

Chelos

Yes! (Also guar combat and guar housing!)

The sad thing is, as riding is now a set of skills and not a limited resourche balancing act per animal, it's kind of nonsense once you maxed out.

Yes! (Also guar combat and guar housing!)

ZOS has confirmed plans for horse racing, so you could simply use your guar in the horse race.
Will be pretty amazing outrunning all those white imperial stallions on my Guar!
