Hey Colin,
First of all, the game can be played absolutely free if you play your cards right. I have managed to upgrade all my equipment and make Master without spending a dime, and it only took about two months. The ads, while annoying ,are no different than any other free site. Now I'm not one to tell you not to play, but this can be a good experience if managed properly. We have all suffered some frustration at times, but it is what it is.
If you do end up getting booted, stop back and tell us where you found a better time.
Adios
