However, with the way the game is coded at its most basic level there isn't a way they can make alliance wide songs (or spells). Spells are either, enemy, enemy AOE, self target only, party targetable, party AOE or "can target anyone." There is no "alliance only" setting.
It's why dancers can Curing Waltz cross-party but not Healing Waltz. Curing Waltz can be targeted on any PC in range. Healing is party only. There is no middle ground as has been explained by the devs is the past.
(Not saying there SHOULDN'T be an alliance level, just saying I highly doubt it will ever happen do to coding realities.)
