Without all of the details, and possibly without all the "early wave" units spoiled, who out there is theory crafting their first army? Things will change in the coming month with new details and new units, but heres the general idea of my army without crunching specific numbers or cards.
General Veers
3 units of Stormtroopers
1 unit of Snowtroopers
2 units of speeder bikes
1 At-st
With the spoiling of Spec Forces, they may take the place of the At-st, with another squad of snowtroopers or 2 units of spec forces if they are awesome.
