I have found the 3 classes my group have tested are good overall. The mesmerist has felt a little over powered at times with the no save versus stare. Especially when the average monster has a relative low will save as it is. The adjustments made to only one stare at a time has fixed some of the issues in my opinion. The spiritualist feels more like a watered down summoner at times but it is enjoyable. The occultist is by far the best class seems well balanced over all and able to handle most situations. My group has played from 4th to 17th level and have left all of our house rules out we have had many arguments about the meaning of the rules. We are in the process of writing out a list of concerns and issues we found playing each of the three classes we played and I will be adding a post about that at a later date. The game has been ran with mesmerist, occultist, and spiritualist only no other party members have been allowed. They have fought undead, daeomen, giants, dragons, and constructs. It hasn't been easy it has been hard some enemies that would be easy for a normal party were hard to kill, while some that would be a cake walk fell with ease. So I have to say I am well pleased with the new rules and can't wait to see them when complete.
