Today highst level in Anathema is 71, and those are 3 people. We have 3 70 lvl and all lower than 70. In january we were max 67 but i doubt so.
Is AB the only place to exp? Well no, we stay most of the time in loa and exping time and quality doesnt change in time.
U overestimate our levels.
About siege, yes we took our chance and got the castle.
