Galactic empire!!! Name a weakness that isnt to do with water!!!
Air is still only imprtant in tech 3. The Empire have now had their penalties for building air removed. Air in T4 is still a downfall of the game, as it is too easily countered, and the air cruisers are only good for taking out infantry (big deal).
Empire can still compete in the air at t4, they just miss out on shielding.
Troops,siths are not that good
