I agree. I know there is a bunch of Elf fans that want elven re-unification and what not and everyone to be a big happy family, like in the pre-sundering days.. but I'm okay with high elves having different elements and facets.
I'm okay with there being blood elves, and high elves, some high elves okay with blood elves and wanna convert em, others hating on us and preferring their alliance "human potential" masters /rolleyes. It's all variety right. And it reflects teh complexity and nuance of life. Makes interesting stories and situations, and eventually makes you really appreciate it if they do come together.
The lore is meant to be an asset, not a hindrance for us getting cool customisation. The distinction between the elves was always just for ingame purposes, blood elves had blue yes anyway, but the knowledge of what the customisation mean is also a boon, as it helps your character get into the fantasy.. it's a shame not that many races have set customisation like Wild hammers, Illidari, etc that have serious lore behind them.
And blizzard should really look to giving certain groups like Farstriders amongst the blood elves and Highborne amongst the night elves unique customisation that distinguish them.. as we've been discussing in the Night elf thread - it gets you more engaged with the fantasy. So I fully support.
