I bought premium, and my name is on the front page for helping with the freedom academy.
Premium is really worth it, you get so much more to the game, and once you get to level 30 carpentry, it only takes an hour to build a 4x4 house.
If you have a mallet or hammer with a WoA enchant, it really only takes 15 minutes to make a 4x4
I suggest finding a good village in golden valley (The free server) to learn the basics, and then once you get into the game, you should buy premium.
Freedom is for people who like to relax, and Wild is where villages are constantly at war, and you cant walk on the roads without getting robbed.
