Referring to Diablo III’s freeform respeccing options, Jackson said that when you can change your mind at any time “the attachment that you have to your character you’re building and your fantasy isn’t nearly as strong.” He concluded that Diablo IV’s respec rules will be “somewhere in the middle” of Diablo III’s laissez faire anything-goes respeccing and Diablo II’s more rigid “choose once, no takebacks” approach.

If that’s got ya concerned, Jackson also stated that respeccing and character building options could be revisited in the future based on player feedback.
