In some of the screenshots from the alliance side of the 5.1 quests, you battle some blood elves, "Horde Priest" is the name of the mob (I think the images are in the "Purge of Dalaran" thread somewhere) they have blue eyes instead of green. Does this mean that thanks to the reignited sunwell Blood Elves are loosing the green tint in their eyes? If so, I think it is a very interesting development.
Would this mean more customization options in the future?
PS: There's also another blood elf mob with blue eyes, the Sunreaver Frosthand in the Dalaran Sewers (I think that's the name) but I assumed the blue eyes where due to frost magic.
