I'm new to BattleLore and I realize things may shift a bit for 2.0, but I'm curious how the game handles expansions and army building. I recall from a video I watched that in 1.0 you had prefab armies but in 2.0 you'll be able to custom build using a points system (a la 40K or X-Wing). Did previous expansions allow you to add on to your existing army? Do you need, or benefit, from having multiple copies of the same expansion set (other than playing extra large battles)?
