Encrypted Memory Cores drop from command crates, so instead of complaining about goldsellers and 4 years of grinding get your 4 letters up and do some work. Craft some items to sell on gtn, do missions to advance in command ranks so you will get crates. No one promised life to be easy when you grow up and leave parents house. Yes they are and should be exclusive to players who already "know how". Remember this game is not and never was p2w but i just cannot help of your laziness. Sorry for being so offensive but there is no other way to explain things to one naming SWTOR p2w game.
