I like to hang back and let others buy up the packs, then scramble to sell em on the real cheap to try and get some stubs back when they get the dreaded 'dud pack'...Then buy up a ton of em and sell em after the market bounces back...I'm sure others are doing the same...
On a side note, I can't see paying 50K for a guaranteed diamond -- personally...There are 2, possibly 3, that would get you most, if not all (Trout and maybe Cutch) of your stubs back - if you're looking to sell em, that is...Of course, getting a good selling Gold with the pack helps...
I too think Arenado, Frazier and Machado
could get to diamond..Machado only needs a small boost in contact and power, of which he is certainly still displaying...
Happy Packs, everyone...
