Taking the risk of beating up a dead horse, i'll have to address the issue with this:
Come on Arena Net... This again?
Look, here's the deal, the skin is kinda neat, and all, but it's not GREAT, i might use it on my mesmer, because mesmers are peacocky and all, but that's it...
Now do you really think that a SINGLE SKIN is worth the same amount of gems as a pack that holds an outfit + glider + back skin + dyes + Total Make Over Kit + Unique-ish weapon skin, not to mention the same value as a pack of 5 different mount skins?
Did you sell enough of the Warhound to make you think that people will buy stuff at this price? I personally saw like 3 Warhounds in-game since they were released, so i'm assuming not that many were sold.
Or is this pettiness over the feedback on the previous mount skin release?
