I will not spend gems on the RNG mount system. I would spend gems on mounts if and only if I have a 100% chance of getting the mount I want. 2000 gems for the Reforged Warhound is reasonable imo because (1) it adds new visual effects to the engage skill and (2) it's a substantially remodeled (same rig, though, which I don't mind). 400 gems for a reskin and more dye channels is not worth it, especially with the RNG. Mounts are arguably more useful than Gliders. I haven't purchased a glider because I don't use them as much as I do mounts. I am interested in mount skins, but the RNG and somewhat high price outweighs my interest and will to buy skins. 0/10 for the implementation of mount skins.
