There is no 'dark theme' at all around them, they just are represented as "What if Stormwind Soldiers were dogs" ?
They -could- have been cool, if properly represented, but right now in Legion they're bordering on the same line of 'silly' the Pandaren suffer from. They just look like furries without a cause or purpose. So to me they're not fitting into the Alliance, because they seem to keep getting represented in that noble and pristine core theme the Alliance has, which makes savage wolves look more like tame dogs.
Their theme of savagery and a touch of the Wild Gods would've been able to come to the foreground much better as a part of the Horde, in fact they'd have a great thematical synergy with the Forsaken as allies.
So to me, I can't take them or their storylines serious. I'll just ignore it as it exists currently and hope that a warcraft 4 either has them breaking away from the 'white priest'-theme that they are forced under as part of the alliance, and either become their own independent faction (as Gilneas always has been lorewise) or see their more suitable fantasy of savagery and wilderness supported by the Horde.
