Personally, HoBS being non unique was insanely broken. In 3 rounds a naked mage could swing 9 dice, for free, then cast a temple of light and repeatedly cast FREE 6 dice attacks with light damage and a daze stun chance evry single turn. Busted. Straight up busted. Attacks like that weren't balanced. The nerf, though really hard on the holy meta at the time, isnt that much of an impact anymore since the 2 expansions its recieved.
Maybe yhats just me tho.
