I think with the points change to our units in conjunction with the lower costs of other battletomes we are getting forced into Hag Narr even more. There isn't much to gain, if at all, by taking other Temples.
I kind of hope for a new Tome with some new units that give us some flexibility in list building. Also faction terrain and endless spell/prayers.
I don't know if it fits the thread, but what do you think would be a cool addition?
