Can someone explain to me why a Elven Ranger cannot fulfill the prereq by taking Energy of the Wild I but an Elven Bard can become an Arcane Archer by taking Energy of Music I. So a Ranger has to expend a feat slot to take a practically useless feat (Mental Toughness) a Bard would not have to expend for the same prestige line? Seems a little off.
Rant done.
