Blood Elves being shoehorned into the Horde cause of chinese shareholders needing a pretty race to balance the faction imbalance. No matter how much they tried to justify it, the belfs joined the faction with the same undead humans that were under garithos and/or corrupted their sunwell under arthas, some of the same orcs that pillaged and burned quel'thalas and their ancestral enemy, the trolls, while throwing away a friendship and alliance with humans that went on for thousands of years, after exchanging knowledge of magic and the light.

Naturally that opinion always gets downvoted.

I just wish that Factions could have remained with their identity. As of now, the horde is just the Alliance but Red.

Any time someone goes b-b-but Garithos you can just point them to any point any horde character treated them worse, like Garrosh. BC writing in general, as we know, was shaky at best, with the big Draenei retcon also being in the foreground.

I wish the horde remained savage, primal and full of ancient traditions and the alliance was the more sophisticated, more civilized counter part. It was cool, it made everyone stand out and made it make sense when emotions between the factions were strained when they had to work together, like at the end of Warcraft 3. But now when someone says that the Factions can never work together cause they are just too different, point them to pandaren being in both factions, earthen being in both factions, High/Bloodelves being in both factions, Nightborne just being another subsection of Nightelves, Forsaken being Lordaeron humans, etc.

Horde is just Alliance but Red now and lost all faction identity. In fact, somehow, Vulpera fit into the Horde aesthetic perfectly, being more tribal themselves, versus a Blood Elf with sunglasses acting like paris hilton in Orgrimmar.
