We pretty much have the full picture. KOTR rewards, which were almost the only reasonable way (short of a bluestacks scripts to non-stop do Exhibition matches, which would lock at 100 picks/cards anyway) to get PP sets for any type (besides the $25 pull, and that was just 1 legendary or epic, not a set). With the nerf confirmed to do away with pairs (which obviously means all other rewards are at least reduced 1 notch, if not more), it would take one HELL of an increase to the drop rate.
If I remember right, someone pegged the drop for a Legendary drop at ++ maxed level at 0.02%, which puts the drop rate near "never happening" mode. There have been people on here with 8000 games and no pulls above UR besides freebies, and put all of that together and you're basically screwed unless you either have $1,000's of dollars to dump into the game or already have the PP sets needed to dominate (as in the best 8 and best 2 Divas).
I've liked this game a lot. I've logged quite a few hours into it, but nothing like others. I had actually planned on throwing some money their way for a mega pull, just because they deserve it. Still, this is enough for me to say "Screw this, this isn't balance but greed, and I'm out", because well, that's what it is. It drops it to 3 ways to get upper tier cards:
Farm nonstop and hope you get lucky
KOTR every 2 days and hope you get lucky to get 2 of the same as rewards twice in a row
Give them all your money
That's greed. /u/NWGameDad_CD , if you're still watching these forums, right now would be a REALLY nice time to jump in and explain things, otherwise you're likely to lose a LOT of players and their money over this.
