All things that belong to the blood elves now, not to high elves. Are you saying that high elf culture is still just blood elf culture and the differences between them is on an attitude level? I can see that as being true. They still try to be elves but they're still also sidekicks to humans
Not really. Yes the high elves live in many human cities, but so did the trolls in orc cities - does this mean they were orc sidekicks??? No. Yes blood elves and high elves may appear almost identical, but sorry, that is so hideously far from true.
High elves and Blood elves are different enough.
a) Physical differences in terms of skin colour and eye colour
b) Stark political differences and loyalties in terms of alliance and horde respectively
c) Change in values & priorities. Many of the high elves had to sate their magical addictions without the aid of fel energies. This means that whilst the blood elves turned to the power of the fel to draw their power, the high elves turned to meditation, the holy light and counselling in order to help alleviate the pain of having no access to the sunwell that they became so dependent upon.
d) Yes, they could now be classified as separate species. The distinction between two species is established by the test of interbreeding. In this example, it would be whether a male high elf and a female blood elf (or visa versa) can successfully have children who are then able to have more children of their own. If the answer to this is yes, then they are indeed the same species and hence the same race. However, after the blood elves spent years absorbing the fel energies, their genetic material (DNA) most likely has been fundamentally altered - resulting in their eye colour change and probably numerous other non-appearance changes could prevent them from producing a viable high/blood elf cross child and hence, defining them as separate species and NOT the same race.
This means that there is a lot of scope for blizzard to introduce high elves as a totally separate race in WOW.
Plus, with the new models being introduced for each race in WOW sometime in the near future, high elves and blood elves will be different enough to make both enjoyable, but both complenting each other in a lore sense.
As we have seen in 5.1 and to come in 5.2, the high elven lore/action often links in with blood elven lore/events, and for me, one is not able to be developed completely without the other taking some part in the plot.
So yes for high elves on the alliance - especially for ending the compulsory 'roll horde or forget your elven paladin'
