One of these, is Tabula Rasa's clone system. A discussion on the topic sprouted up on the Planet TR forums on the topic, with the OP going so far as to call the cloning system Tabula Rasa's "lady in a red dress." While I was not sufficiently persuaded that the thread wasn't just an excuse to make a Matrix reference, I think the larger discussion is a salient one. Does a cloning system like Tabula Rasa's really represent a cure for alt-itis? Some would argue that it's a boon for casual players who don't have time to level eight different characters independently to the end-game, but who want to see the content. Others would argue that Tabula Rasa's tiered system means that most cloning opportunities save you a negligible amount of playtime - after all, you only have two ways to go with a clone at level 30, you can't jump branches. It's an interesting discussion worth checking out (even if the topic has since wandered a bit).
