I have yet to play them, and don't know if I will really get into them because of the GW style add-on problem. Nothing confusing about which die to roll. The Tactical Cards are not collectable. You get a fixed set, and must choose 30 from the same set that everyone else has. This is part of the beauty and flexibility of the game, as the deck influences tactics and army composition quite a bit.
Online support is excellent.
The minis are excellent. The value you get for your money is good. If you play the CCG or the RPG, this game is a breeze and a joy to pick up. Having played a couple of games and watched several more, I am very impressed with Clan War . Its tactics and goals are slightly different that in Warhammer , which makes it harder to play initially because you have to change your mindset.
