What I learned playing CUT:

I will never spend money with EA Sports ever again.  Here is why:
1.  EA sports blocked my account from auctions and stole all my coins.  I never once bought or sold coins and never engaged in any bad behavior.  I spent $8,300 on card purchases before they dropped the sketch card.
I believe I was personally attacked because of posts I made about ea sports decision making, content, etc. 
2.  While spending this money didn't matter for me financially, I have discovered that the players themselves are very much arbitrarily better or worse.  In all my games (over 1500 games played just in normal h2h) played....i have found that what players you have matters very much the least of all.  Being NMS would be from a winning or outcome perspective as good or better....also, DDA gives a massive equalizer to lower graded teams...never the other way.  And there will always be games where everything and every animation is stacked against you....no matter what team you have. 
It is literally pointless and a waste of money.
Additionally, EA SPORTS hasn't even bothered to fix glitches and bugs....they were notified about the abilities tab in specialists like for kickers and punters and how it's messed up since day one of the first kicker with abilities and they still have not fixed it. 
They give zero "care" about their customers.  Horrible people, fake customer service, they conduct fraud regularly (hence the "make right packs").  
It's just sad they have a monopoly.  This game and all their games could be soooo great....idk what the analogy is but man, talk about ruining something that could be excellent by having bad people, no customer service, terrible ethics and unqualified people.  
1000% would recommend that you make a pact to just never buy packs as it is addicting and know that you are not only wasting money but supporting the worst of humanity.
