Honestly, if the pack was split into types (raptor, springer, jackal, taimi's floating head, griffon), with a pick one of two, three, whatever arbitrary number? I'd feel more alright on the issue. If there were mount skins I could earn by actually playing content, I'd feel more alright about it. If you did both, I might even consider spending monies to get the one jackal skin I do kinda like.
