What I really want to see for G.W. is dynamic unbalanced battles. I would love to be able to preconstruct units to invade a planet and be able to fortify planets before a battle too. Ideally research would change so that your faction would need to choose what tech it wanted to prioritize and taking key planets to gain perks and resources to further your campaign. Blow up a planet during a battle? Well now you get less resources for your effort. You would get battles where its tanks vs bots+planes and you really wouldn't know what you were walking into when you invaded a planet without sufficient scouting through the galactic map. Another cool feature would be something like a commander factory or tele that would allow you to bring other players into battles slowly escalating the conflict until you wound up with massive battles between clans/factions involving a large amount of players. If implemented correctly G.W. could make this game one that will go down in history. Clans will have stories of how they were pushed to the fringe of their territory but a pair of bold commanders went on a crusade to reclaim territories. People would tell tales of how the 30+ commander battle for the clan home-world ended with both sides nuking each other into oblivion. Perfectly symmetrical games are fun for e-sports but battles with disadvantages because of grand scale events are better
Fortifying a planet is not how it works in PA. If you have as little as 3 buildings at the start, you have a substantial advantage over your opponent at the start of the game.
You kinda missed the gist of what I said. Fortifications would be done from the galactic map with limited options that way its not 1152555 tanks or turrets vs a commander. Attacking players would also be able to start with units at their disposal (if they choose to invest in it) so that they have a secure foothold to begin with. Ideally the attacking player would be able to spawn wherever they wished to as well.
