I have to concur. Im finding "premier" very bad value since you really are not getting much more than the basic. Sims DLC's as a subscription would make it worthwhile as there has not been a game released on Prem I have even wanted (ok wanted Anthem before it came out, but not after it came out because it was so bad would not have bought it). BTW the Sims 4 Deluxe is part of the BASIC package, theres no additional content by being Prem.
There is also not much on the horizon from EA thats interesting, I think Dragon Age is it. So most likely will be downgrading my sub to basic when this one runs out unless EA step up their game to include Sims 4 DLC's
