Trolls are the most xenophobic race in all of Azeroth. Vol'jin and his Darkspear don't represent Trolls as any majority. Their being so un-troll is why they are snubbed by other Trolls...
I'm gonna have to agree with this statement for the most part.
The only possible exception used to be, besides the Darkspear I guess, the Zandalari. They still had a superiority complex but it was more like "Hey, we've been around forever kid." then "We are better then you lowly grub."
I genuinely enjoyed questing for them in Zul'Drak, they seemed to see other tribes as self destructive and crazy and here they were trying to preserve Troll History for the sake of it.
Before that they were attempting to stop a God monster Loa thing.
Then Cata comes around and they're hit with the generic "slaughter the trolls" bat.
I think Troll Paladins could focus on the more bloody aspects of Paladin culture. While the Draenei and Tauren and Humans focus on the Light and the good things, Trolls and Dwarves and Blood Elves do more of the Vengeance and Judgment aspects.
That's an assessment largely up to opinion.
Unlike most Paladin Orders for instance Hand of Argus Vindicators are almost entirely militaristic in nature rarely showing the gentler side of the Light. I think this is fairly well shown in the limited contact you have with them in game and in the lore.
Whereas Silver Hand Paladins for instance, mostly in the novels, are shown to be just as much the gentle Healer as the fierce combatant.
I like to think this difference stems from the environments Draenei and Human Paladins developed in, I also tend to think the Draenei Priest and Paladin organizations developed alongside each other rather then one springing from the other.
My but I used that as a tangent didn't I. Main point being even the more vengeful and warlike side of Paladins is rooted in the classical "good guy" theme that I think may have had a hand in leading Trolls away from their traditional practices.
Why else refer to them as heretics if they were simply doing the same old thing with a different type of mojo?
Because they have lots of sparkles and glitter, wear pretty dresses, and do pirouettes.
We are by far the best looking class, despite your mocking jest.
Race wise they are limited to not so interesting races on the Alliance.
Well I strongly disagree with that one.
