Literally the worst idea I have ever heard for revamping the store..
especially because it sounds so much like something EA would do 
OT: I've never had a problem with the store the way it was in this game, except before the introduction of level 4 consumables, inifinite gold character cards was bullshit.
Only thing that I'd change is making character respecs not tied to RNG store cards. Those should either be free or cost a set amount at the reset screen whenever you want to do one.
Those were the days of unlimited XP cards and also iirc they used to only offer 100k XP instead of 250k. I'm glad they fixed that and started giving us level 4 equipment.
I feel respecs should have had the same priority as supplies and only once you cap them do you acquire a random equipment. Capping the amount of respecs to 3 was a mistake. It seems harder to get them when they changed the status to uncommon. I do wounder if respecs would be as hard too get if they were still a rare.
More pack options would be a way to improve the RNG, like adding in a gear/weapons mod pack that prioritize them over other rares, kinda like the AP and RP.
They should have kept the Premium Veteran Pack and Resurgence Pack.
Filter packs for each DLC would have been very helpful for newcomers starting after the release of all DLC.
