I think you are right...
When you look at the Quick Sell values and the price of packs, etc....the market NOW is probably more where 2K envisioned it from the start.
The early dupe glitches and farming inflated the market...and its very likely that many of those who used these loopholes didn't spend wisely - so now that loopholes have been patched, they have nothing left to do but cry and complain.
MyTeam needs some things fixed...but some of the reaction of late at how "hard" it is to get MT is nothing short of what I would call some players being "crybabies".
Some people think they're entitled to access to every card...and that is the ultimate point of MyTeam....and that's just silly.
