See, you say that like that's not 460$ minimum when you can build a deathlords army for 100$ less and still have some skeletons and hexwraiths left over, or a full beastclaw army for less than half that, or fyreslayers for 100$ cheaper, or ironjawz for 50$ less.
Don't get me wrong, it's great that they did the box, but if they could drop the 170$ Magmadroth+vulkites down to 85 then getting the Daughters box down to 70-80 shouldn't be unreasonable.
As an aside, when I first saw the daughter box I went 'aw cool! I'd love to start that army! if it's like 40-50$ I'd totally buy it! And it should be right? The infantry should be like 35 and the shrine should be 50ish so with a decent discount...' then I looked up what those boxes actually cost and was full of sads.
