I understand it's meant to be random, but it seems like the third upgrades have been completely taken off the table (at least for me). I'm going on dozens of packs now with no third upgrades--and I'm simply not the type to be so phenominally lucky with all my other classes to have gotten the upgrades within a few packs of opening. :P
Even still, I don't think it's totally random, the game really does seem to try and give upgrades if they're available--I've been reliably getting the first two within one or two packs of unlocking a skin.
360, if that makes any difference.
What does the 40k pack award if you already have the non-Rank-10 variants unlocked?
