I enjoyed the cutscenes for Darkshore; to me that was an attempt to return to the roots of night elves being this wild, aggressive race, the fearsome predators of the night.
I think they went off the tracks all the way back when they decided night elves were going to be THE ELF for vanilla WoW. So they had to morph them into the wood elf and high elf lore that was popular for elves at the time, rather than letting them be their own creation as they were depicted in WC3. You can see this most especially when you compare them to the BC characterization of the “actual” high/wood elf race, the sin’dorei, in that…well, the sin’dorei are no longer that trope either. Even though WC2 lore solidly puts them as having Legolas-like rangers and Light-worshipping priests, the storylines in Outland were all about their aristocratic magical politics instead, and even the redemption of the paladins never reached back to those roots.
Especially now that Sylvanas is gone, Alleria is back, and the void elves are somewhat of a big question mark, I think they need to move that wood elf feel back into sin’dorei, or possibly ren’dorei (and quel’dorei, with the SLs customizations on the horizon? HYPE!). The War of the Thorns, whatever else it was, is a great excuse for the night elves to go well and truly feral.
I agree with what some of the other posters in here said though: I don’t think the nelves should be directing their ire at the rest of the Alliance. Internal faction strife and warfare is starting to feel really tiresome after what Sylvanas pulled. If they make a campaign like what Horde got, but more so, with players able to choose between being loyalists or not, with some different outcomes and rewards for doing so, well, MAYBE I could see the appeal of Alliance having a similar plotline of split loyalties too. I highly enjoyed played through the BFA storyline on a Forsaken character, but I wanted MORE of that kind of choice. (Also that at first, you were forced into being a bad guy; the choice between Sylvanas and Lorthremar should’ve come much earlier, because it didn’t make a whole lot of sense for anyone BUT a loyal Forsaken at first.)
