Up to 70k power by being f2p or low casher you find the game actually nice, but when you reach the 70-90k region you begin to experience the existance of an unsurpassable wall and when you reach 100-110k you understand that you can't do any single mistake of any kind just to stay on par with your common enemies.

If you plan to start in a new server and to continue to play theb my only suggestion is to NOT do it in la region. Select another region even if is not in your timezone because LA region is highly unfriendly towards f2p and low cashers mostly because every cross server feature is cross server with every server of the region and not limited to clusters like other regions have.
