I am a fairly new player, in the past two months I've achieved level 65, and noticed a trend, which resulted in me cancelling my subscription just now.
All of the items I find to be desirable either currently exist, or used to (only) exist, in the Cartel Market.
This means that, unlike games, we are not playing a game to achieve items, we just sit in our respective fleets, take out our wallets, and gamble against an unknown, unaudited gambling algorithm, until we get what we desire. With the implementation of these cubes, it's hit a new low.
I am going back to a certain game with a huge subscriber base, a subscriber base that is retained as they understand something that EA do not: Players want to play the game, players are not here to play in a casino, players wish to obtain items based on skill and merit.
Speaking with your wallet is the only way EA will listen, I suggest you all do the same as myself and cancel your subscription (else, do not buy Cartel Market items).
