Eh, not gonna call the nightborne thing a cop-out. I'm just gonna see it as a plot-hole as to why the blood elves can't have some fruit, too. '.'
Otherwise, that's what what I got from the blood elf deal. They are still addicted to mana and need their Sunwell - it's just that it's been restored, but with Light rather than Arcane (Or was it Light & a bit of arcane?)
