No Space Battles

Has anyone really expected this? This is Battlefront, i.e. ground/air based conflicts. You can only complain if the name was "X-Wing" and there are no Space battles or Death Stars.

ATAT's on rails

This would be a nightmare to balance. The ATs are very powerful and whoever controls them will basically destroy the entire team. So you either nerf the ATs drastically (thus destroying their status and purpose) or you scripted them in order to allow players to escape them

Cut split-screen for PC

How is this a problem? How many games have been released without split-screen? Do you recall Call of Duty, Battlefield or any other AAA shooter, having a split-screen multiplayer? Can you really experience a multiplayer game with fast-paced action on half a monitor? If there was a co-op - sure, but as is, its not really a pain.

Decreased level destruction

Pretty graphics take priority. I'm perfectly fine with that, excessive destruction (e.g. Bad Company 2) is not pretty and with 40 people most maps would look like shit. Granted this is a battlefield and as such its supposed to be leveled after 40 people fight each other, i can see why they don't want to implement it.

I'm all for criticizing a game, but it seems the gaming community starts nitpicking everything with a fine comb. The game is made by the people who created Battlefield. What do you honestly expect? Light saber fights? Force choking? X-Wing fights?

You'll get Battlefield in StarWars theme, just better. And if that's not the game you want - that's fine too, StarWars is a really big universe and having a game that can show every aspect of it, with polished visuals and interesting gameplay mechanics is nearly an impossible task.
