I loved the Beta but I am a core Battlefield fan so it's to be somewhat expected.
1) Yeah this happens in BF games with spawning on teammates or even randomly. Not as bad as other games I have played recently but enough that they should tweak them.
Drop Zone had some pretty terrible COD style spawns and associated spawn killing.
2) Rarely had an issue with bullet sponges, a couple of games here and there but nothing major. Certainly nothing compared to some other games. That being said, they way they did their matchmaking was interesting.
Matchmaking and balancing could do with some work, mostly team balancing in terms of numbers.
3)Yeah they could do some tweaking with the pickup system based on which side you are on, mostly for Walker Assault. (although that Smart Rocket is good against people, towers and fighters not)
However what I have noticed from many Beta players is that most Rebels refused to PTFO, wouldn't work as a team or wouldn't use what was available to them to win.
This is imperative when the entire objective of your team is to stop the others advance, not kill them, stop them using the available means and specific actions.
(can also blame lack of in-game chat for teamwork etc)
4) Testing ground for the Beta was Survival for me, only one difficulty setting and short duration made it easy to work out the gameplay.
Sure there will be such a thing in the actual game, don't remember many MP only Betas having tutorials but I imagine they wanted to keep the Beta size down so excluded many things.
5) I can understand why people dislike this.
While I agree the weapons effectiveness does not reflect the movies, I would be rightly peeved it they actually were as ineffective as they are shown.
We could also make that comparison about any weapon from any game that appears in any movie - some seem to have no clips, can't hit the side of a barn and seemingly can't kill good guys - but I understand it is a movie with no real world or gaming application.
Perhaps they could be less accurate however, why would you want to play a game where the guns are ineffective outside of mid -range or CQC ? It would feel like Star Wars: COD then.
Engaging others at longer ranges is essential on larger maps with larger populations to reduce area flooding and encourage gameplay across more of the map.
Players can have longer distance, strategic battles dodging and ducking to outmaneuver instead of blasting from the hip at close range like many other FPS games - it wasn't just another chaotic CQC FPS like AW, BO3, Destiny, R6 Siege, etc etc
This can tend to lead to players only going for distant engagements and causing the game to stagnate - but that's like any game - choose to PTFO or just go for kills.
A humorous general observation: In COD people complain about guns shooting like lasers (accuracy), then in Star Wars when laser weapons shoot with actual laser precision, many people complain or say they should shoot like guns
Much of this is a general response to the Beta feedback not just yours
