Did mythic ever state the reason? If so, can somebody post or explain it for me?

Now, I'm a nobody, duh, but I've been always hoping for Valkyn to gain access to shaman. There are several plausible reasons aside to their awkward animation
.Suffice to say on the RP side, shaman deals with earth-tribal crafts and Trolls and Kobolds are just the right ones for this. Also, both Troll and Kobold have access to Bonedancer and Shaman.
Dwarves may be living in mountains and stuff like that too, but would it be more plausible if Valkyn had the access?
Along with that, Valkyn already has somewhat caster stats xP if it weren't for the "useless QUI", in this case.

Jesus k-rist, I even told Matt Firor about frigging Valkyn Shaman when he was at the Games Convention in Germany, Leipzig few years ago.
