Gunlines ahoy, unless you deploy in disarray.
Battle lines? Shore up to cover and pray that Luke/Vader/ATST/ATRT breaks the line or your Bikes/Speeder manage to choke out a flank.
Long March? Get stuck.
Major offensive? Draw that arc line, the left flank must hold!
I'm looking forward to the addition of artillery, so that we can truly make trenches great again.
All kidding aside, I'm looking forward to some true linebreakers. Tanks will be a good change, as will melee. Can force a more guerilla style battle.
