All of my characters absolutely hate it;
Quincy couldn’t stand it when the Sin’dorei allied with the Horde in the first place, and had no trust in Sylvanas after seeing one too many hypocritical actions. Losing family to the Amani made allying with the Darkspear uneasy, even if they were a different group.
The mind control shenanigans in Silvermoon were also something else, and the fact Lor’themar even allowed that in the first place soured their opinion on what Quel’thalas has become.
Theramore was actually the line for them, but they couldn’t say or do much to defect on their own because of fel corruption making it almost impossible to blend in with Quel’dorei, so they just conspired with other wanna-be defectors until actually getting a chance to formally leave with Umbric’s group after the… accident.
Rejoining the modern Alliance, not the one they originally knew, made them realize even more how big of a mistake Quel’thalas being allied with the Horde is; even as something afflicted with the void, they’re able to prove that no, they’re not some sort of monster, and that they have a place without needing to continually brutalize former allies that had nothing to do with Garithos or Lordaeron’s betrayals.
If they’re going to be a cog in a war machine, they’re not going to be a tool of blood for the sake of thunder. Retreat is an option if victory isn’t at hand, and you don’t forsake your former allies and students for the same people that put you in a horrible situation to begin with.
If Silvermoon is ever a target, they’ll be demanding to help command troops on the field so they can take their home back from an appointed tyrant that continually divides their people, and a group that’s caused pain and suffering for even their own.
OOCly, slapping the other side right after you both helped each other is the most Warcraft thing possible, so I’ll be raiding and doing M+ with my buddies, then ganking them right after because it’s funny and a part of the spirit of the game.
Telling people that this isn’t so is just ignorance to what the game actually is, and it’s been annoying since day 1.
