I am a complete newb to Sacred, but I just bought Sacred 2 Gold since this is a genre that I usually enjoy (Diablo 1/2, Titan's Quest, Dungeon Siege 1/2/3, Torchlight, etc.) Is it recommended that new single players always use the CM patch? I.e. do the bug fixes outweigh the gameplay changes and/or are the gameplay changes sufficiently minor as not to detract from an enjoyable first play through? (Changelog notes like "added new feature: sigils" and "buffed bosses" scare me a little ...) Are any known newly introduced bugs unlikely to be game breaking? Or, conversely, is the CM patch really intended for experience players looking for more challenge?
