So currently Blood elves are the only race with 3 racials, all others have 4 or more, actually they've been ever since Mana Tap (i miss you) was removed in wotlk. So as Sunwell is restored, like many years ago, maybe 4th blood elf racial could be somekind of active buff, something like "Blessing of Sunwell" or something. If sin'dorei (and quel'dorei) were so reliant on Sunwell why don't they have any racial spell related to it?
