Bob Dylan-inspired introductions aside, what's actually changing with this update? Plenty. The game is adding a new mail system and a variety of new mounts, along with major revamps of the Dominion system and the new Scarlet Bastion PvP map. There's also the new Class Change system and Astral Modifiers to ensure that you really feel how much the environment really is, well, changing. But you don't have to take our word for it; you can watch the trailer just past the break.
