I've played a lot of large starship space combat games like Battlefleet Gothic and Star Trek Attack Wing and I would like to see a planet token and planetary missions for Armada.
I don't find the current dozen missions very epic. I want fleets fighting over possession of a planet or blockading a planet or landing troops on a planet. Battlefleet Gothic had several great missions involving planets like Exterminatus and the planetary landing missions. Star Trek Attack Wing has the awesome Siege of AR 558 mission where you simultaneously try to beam troops to a planet and fight off an enemy fleet in space. Here's a couple video batreps of the Siege of AR 558 in action:

I would like Armada to get planet tokens and have planetary missions too. I would like planets such as Hoth, Endor, Tatooine, and have epic battles over their possession or blockade running from them.
