For me I think its a good culture marker, I’m not saying all Blood Elves are Sylvanas loyalists, but they next to Forsaken have been portrayed as some of the main supporters in Orgrimmar etc.
Where as Alliance High Elves have been anti Sylvanas since WOTLK and prior probably, the way Vereesa has stood by the Alliance is a different reaction from the Blood Elves seeing a common ally in Sylvanas when they entered the Horde. Where as Blood Elves seem well integrated in EK Horde, even having an Ambassador in Sylvanas’s throne room for years before she became Warchief, just from my perspective I think it shows where Blood Elves view things and people, and situations vastly differently then the Alliance High Elves, and their different perspectives is a nice pin pointer in the two respective sides they choose to identify on.
