[The B.I.V.]

I think once common squads are introduced in AotP they'll be 1-life units and we can more easily compare them to heroscape units.

One (inherent) problem with AotP is the fact that you have to include a Planeswalker in every army. That means when designing new units (and trying to incorporate heroscape units) their point values need to mesh with whichever Planeswalker point value so as to nicely make a 500 or 600 point army, that limits things a LOT. For example, if I want to use a unit with Nissa, it's point value needs to exactly equal either the Elementals or the Elf Archers...
