i think the issue is and remains that DICE is scared people will grind out any upcomming seasonpassout so fast that it becomes irrelevent what and how much is in there.... at the end of the day a seasonpass should be just grindy enough to make a 08-15 player with disposable income cash in to skip the grind.... if XP farms were there noone would pay for boosters or streight up buy the stuff outright...
also any weapon that will be introduced in a season pass i sbound to be overperforming out of the bix to give incentive for players to grind as fast as possible i.E cash in....
EA will find every possible option to milk every last cent out of this game to appease the most likely ver very pissed investors
