Interesting, thanks for sharing. I thought it was a n excelelnt choice to have a darker spiteful vile race (using classic's opening narrative of the darkspears) in the horde, it was unique and the exception , which ahs its place.. just like i unlike some felt it was also good to ahve a near flawless race in the night elves - people may hate either of this ( yes, i hate evil and dark) but they have their place because both are possible, and you can have mmean spirited people who do vile immoral things but aren't necessarily wicked or villain bad. This is where i thought the darkspear trolls would sit.
Howver blizzard really have messed up their portrayals of both trolls and night elves. We never saw the trolls every exhibiting any of those characteristics they are described to be like, in fact we only see the good an honourable side, we don't see them even progress from a lot of bad to cleaning up a lot of that, but still have that vengeful spiteful side tot hem.. blizzard just didn't show it - maybe they wantedt he horde to be more popular, and thus trolls and blood elves who were also supposed ot have an evil ambitious reckless aspect to them was either rarely shown in the playable race with the opposite in fact showing up far more commonly. I'm fine to have exceptions to the norm, but when you spend no time characterising the norm, that is problematic.
night elves similarly, perhaps because they didn't want them more popular, instead got lots of flawas and inadequacies, the titanic race they were positioned as and described as in the WC3 manual and set up with even in WotA tirlogy (which also nerfed them, because a 200 year war against the legion by their own hand turned intno a 2 year affair when Krasus, Rhonin and Brox got sent back in time and effectively saving them, makking them and not the night elves the architect of the legion's defeat), the night elves that we see show up in WoW now are much more flawed and ordinary. Almost like blizzard had no idea to show and preserve how remarkable they were without making them invulnerable and infallible --- funny Tolkein had no problems in conveying an immortal, fair and wise race appropriately great but not invincible. YEt wow did. Sigh - they just didn't try.
I guess you liked some of those aspects of the trolls, just like some are drawn to dark and edgy emo, but others aren't.
