As i saw from rocketbeans there are changes on point system
every kill now is 6 and 7 points.As i understood if your team takes first kill you go 6 then if your team takes second it's 7 then again 7 and again 6 until you finish the game.So we have 6,13,20,26,33,40,46,53,66,73,80,86,93,100.Those were the scores of all 3 games they played.
Other changes are the commands.It seems like the "follow me","need repair","regroup","need backup" are no longer available or they changed hotkey.So we have only "attack target" and "point at target"[again not sure about this,i can't imagine the reason why they block them]
last change i noticed is the tactical cruiser beam amplifier texture.Now it does some small of zig zags
fell free to post any other change you have noticed.Specially from those that have been at gamescom
