You are going to have to show me Where it says this stuff.
Where does it say the majority of high elves were humbled any more than the blood elves? The blood elves work alongside the horde races do they not?
Why would most of the playable High elves not be from the kirin tor or silver covenant? Why do you get to decide playable high elves would be from this faction that had to journey down from quel'thalas and where does it say the ones that had to journey from quel'thalas out number the more arrogant ones in the silver covenant or kirin tor?
I also don't see any lore about them being throw out for refusing to compromise their beliefs and morality. Even if they were that does not mean the high elves who had to make a journey through the undead to be saved by humans had as hard a time as the elves that had to retake their capital from the undead and cleanse the Sunwell which was also attacked by demons.
The artifacts thing is just semantics. Even if its a passive flow of mana they are still draining it and its still them getting it easier by the hands of the humans.
It doesn't matter if they "pulled their weight" I never said they leeched in the first place. I said they were taken care of by the other races of the alliance which the blood elves did not have the luxury of doing. They received items to solve their mana problem by the humans and they helped out cool, the blood elves did not receive help from the alliance or any items to give them any mana so what are they supposed to do if they want to stay in quel'thalas and rebuild their undead ridden homeland? Once again having humans hand you free mana you joining their army but not being in immediate danger is a much easier way out than staying and fighting the force that just destroyed your homeland, having to set your ideals aside to get it done, having to find other ways to get your mana fix and trying to rebuild the Sunwell so they can get mana to everyone not just the ones who get artifacts.
You clearly are just biased towards high elves and are desperate to make it seem like they had even a fraction of the difficulty in their lives that the blood elves did to try to make them seem like just overall better people when in reality the only reason they didn't abandon their morals is because they got help from other races. You even admit this but try to say its ok cause they helped out too. Cool but the blood elves didn't get any help so they had it much harder obviously.
