The reason why it's good is because it is an AoE spell that generates ZERO THREAT.
Get a buddy who can AoE (pref a paladin) to pull a bunch of mobs in an instance without tagging them, kick your friend out of the group and use holy nova on the mobs... They will be tagged by you but will still have aggro on your friend - no matter how many holy novas you cast, this is when your friend starts ploughing the mobs down with AoE, giving you all the exp.
I feel like this might be an exploit. I'm pretty sure it didn't work this way in retail and it would make sense if all XP is divided just like honor. AKA, if a level 60 does 95% of the damage, you only get 5% of the XP.
Mostly it reeks of "too good to be true". I wouldn't do the kicking out of group thing.
