In Heroes II and Heroes I, phoenixes were also available to the Elves, so this is like a return to the roots.
I'm not voting for "Balance" only because one of the elite units is a phoenix and, oh my god, a mega phoenix. :D
Of course, if "Strength" and "Wrath" were combined, I think it would create the ideal set of canonical units for the Elven faction of Ashan. (Judging by Heroes V).
Я - рыцарь, Зверей истребитель!
Я - тот, кто не знает, не ведает страх!
Я - Божий Сын, победитель!
"Без жалости! Без сожаления! Без страха!"
