Learn what? BF4 was being supported by DICE for 2.5 years. Even though the release was bad, they fixed most of the problems and they also gave away free maps for the community. Not to mention that BF4 premium had some amazing maps and weapons itself and the phantom program as well. I played BF4 more than any other fps game in my life. So, i 'll definitely pick up BF1 premium if it does exist.
What I learned from BF4 is to buy the premium the edition. During pre-order, the extra you have to pay for Premium for less than the price of a single DLC. Buying them individually would have been a big mistake if you pre-ordered the game and if you changed your mind later and wanted to upgrade to premium later, it was 50$. If you don’t get any DLCs, you are missing out on 80% of the maps
