I've read many posts by sirgog over the last two years. He's quite knowledgable about the game, and I certainly hope he's correct about Wizards not being completely nerfed.
Last year I TRed my Ranger to a Wizard due to initial changes in Shroud's blades of death. Ranger just died too much and I wanted a character that could farm gear and be self sufficient. I decided on Pale Master because I am not the most skilled player and need every edge I can get.
I have been leveling the wizard over the last month and looked forward to scroll farming and being "uber". With the epic changes, I have to reconsider what "uber" is (obvious answer: MrCow). I just hope my wizard isn't neutered before I get a chance to play it at cap.
If it's no good, there are other classes to play. These notes are from Beta, so things may change. I do agree that "blanket" immunities are lazy, but with the code being what it is, it's probably easier to do that than have mob casters buff their minions. There's suspension of disbelief ("hey, I'm made of wood and metal and cast spells!"), then there is "mob casters have bottomless sp bars and can hit you from around the corner with Hold Person".
I love the game and agree there needs to be balance between classes. I would just like to see balance between players and mobs.
