This was kind of obvious to anyone who spent more than an hour with the game, but it's nice to see them officially acknowledge it all the same.
The admission came from Matthew Everett, one of the community managers working with EA on Battlefront. When a member of the public hit him up and asked if his failure to defend Hoth's shield generators from the hulking AT-AT's was all his fault, Everett uttered words that many soldiers would be pleased to hear.
@Focalin Nope! Its a balancing issue within the Beta.

The lead multiplayer designer, Dennis Brannvall, also said the Rebel experience was too difficult and indicated that the information retrieved from the beta would result in changes down the road. There hasn't been any communication about what those changes would be, but as long as one of them fixes the spawn system they'll at least be on the right track.
