It does look like it's rehearsed...was gonna say scripted. But yeah you know what I mean. Won't play out that way in game. I think it's been done intentionally to showcase it like that, if you know what I mean?
Think it looks like good fun, never played the previous Battlefront. Also judging by all the work DICE have put into BF4 it will hopefully be well supported.
Looks good so far, my only worry is that they make it too much like a Battlefield: Star wars, the simplicity of the old ones is what was so great about them, looking forward to it though very much
