In answer to the question posed. The silly sparkling horse will not stop players sinking their gold/time, into getting other mounts in game. People don't have them just for practical reasons, otherwise the game would be full of people riding around on race appropriate ground mounts, and faction appropriate flying mounts. Everyone would buy the first available to them in each category, and that wlould be it. But go into any city and there are bears (of various colours), Mammoths (of various sizes), Motorcycles, Undead on Raptors, Trolls on Kodos, Dragons, Flying Carpets etc. etc. ect. In such issues players are interested in (deleted as appropriate) variety, asthetics, rarity, and, of course, just having the most. I think people buying this just so they'll never have to bother with another mount are going to be very, very rare.
