Isn't the whole deal with them surrounded by Norse mythology?
The whole deal with them always seemed Viking/Valhalla inspired and as such their class hall.
The whole deal with them is "every race is assumed to have a standing army, so warriors make sense"
The way they get there is different though for sure. Alliance footmen are trained soldiers with swords and shields and armor
Orc grunts used big ass axes and dressed basically like barbarians.
In wc3, 1 grunt would crush 2 footmen and have health to spare. Grunts don't give a shit about Vikings
I think the problem is that all classes have the same class hall when they can be somewhat thematically different.
Warriors for example: Fury and Arms could probably fit together, but Protection is a whole other beast. I could see Vykrul being with Arms and Fury. But Protection? Nah, that doesn't seem Vykrul'ish to me.
Priests are another example; Disc and Holy fit well together, but Shadow not at all.
Outlaw rogues are basically pirates now. Subtlety and assassination are still classic shadowy rogue archetypes but loud pistol pirate guy is kinda at odds
All of druids are good. Mages, locks, any the like I think also have enough similar flavor in the specs that it makes sense to share.
I think hunters actually have a lot of distinction now. Marksman are more like old night elf sentinels. Beast master is like rexxar, survival is some other nerd. i don't think the style they're going fit with marksman would be hanging out with other hunters in any way
