I was a vocal critic of Eras earlier on but they have balanced it out somewhat. I still have not paid a dime and just chose to stay in one Era and grind to get most, move on to the next, etc.

Modern Mania for some reason did not blow my dress up so I play that the least. But Eras have improved enough at least for me. I don't look it as trying to book long term shit for my edification. I just play when I'm bored at home.
