Cons:
-No LAAT/i on the ground missions
-NO Droid Gunship on ground missions
-AI still sucks
-NO free borading and shooting from said gunships (door gunner)
-No truly epic battles
-Generic interiors for the space missions- no exploring a Star Destroyer or Calamari Ship

-Weakened concussion effect of heavy blaster cannons on ground vehicles

-Weakened Jet trooper EMP gun- smaller blast radius
-All classes have the same weapon stats between factions-no more learning the idiosyncracies of the units detracts from game play
-No dual pistols for Jango and no actual clone commander with dual pistols
-No True ARC troopers- Pulse rifle, grenades, remote explosives etc
-Same generic objectives in none story modes
-Idiotic story line
-CTF can go on forever if you don't step in (great for medals)
-Ridiculous requirement for permanant Rocket launcher upgrade (65 times of getting 4 crit hits!!!)
-damage ratios for starfighter weapons are messed up and the infinite torpedoes is stupid and so is how weak they are
-plus ship boarding and dogfighting is not what it should be
Pros:
-Space battles in general is a good addition
-New vehicles and units are cool- to some extent
-Dark trooper's ARC caster kicks jedi ass!!!
-Got rid of Clone pilot's lame bolt caster
-Remote explosives!!!
-Droideka is not a one sided unit any more
-Better explosive to armor damage ratio for the vehicles
-Elite rifle and precision pistol are good additions
-Improved Galactic conquest
-Better details in the maps
-Better shot gun
-Chain gun rocks
-Sniper is no longer super weak
-Wookee is way better
Tell me if I missed any.
