My roommate tried to let me let him play an artificer EVERY FREAKING TIME I suggest a pathfinder campaign. He staunchly refuses to look at it as anything but an extension of 3e.
To be fair the core is pretty much a extension of 3E. Their nothing really in the core that makes it stand out in a major way from 3E imo.
While their is some unbalanced material in 3.5. There is some that is. Too often as some others have said. It's either a lack of understanding. Or were never that broken. I'm in a game with a good DM. He refuses to allow 3.5. material. I kind of respect but at the same time he has never read any 3.5. material. Someone told him that the 3,.5 material was broken and unbalanced. Which one should never take as the gospel truth imo. I once had a fellow gamer insist that DR/2 was not just broken and unbalanced it was game breaking.
