anyway glu can actually publish the percentages of actually getting certain players in mystery boxes, draft, etc.
it honestly seems completely rigged and shady... they show all these options but it is obvious that you really have no chance of getting anything... I opened over 25 mystery boxes and never got anything more than cash or the lowest player. I have opened over 75 #1 draft picks and still not gotten a 5 star player.
as for the collections, you can pay the 100 gold to keep selecting and I have never gotten anything but cash.
In the sluggers draft, I did over 20 gold picks and still never got a 5 star.
Basically the whole thing is completely bullcrap to get you to keep spending money non stop.
if you had to actually publish the percentages like gambling we could see how unlikely it actually is to get each option.
