We all know the game mode is gambling full stop.
But I agree about how terrible pack weight is, I have also opened alot of packs and have yet to pack a single psg player, I have packed Blas 8 times though...
I have spent close to a full day doing sbc's over and over for basically nothing, yes I got a whole bunch of useless shiny cards I will never use in game but isn't the point to progress and improve your team, this is practically impossible unless you win the lottery or spend way too much money in the store.
The mode needs to be classified as gambling, sadly it won't be due to how much of a cash cow it is, too many envelopes getting passed around probably.
