Will movement be “click to move” or free, as it is in Dark Age of Camelot, WoW, and EQ?
Free. If there are any elements of click-to-move, it will be in addition to the free movement, not instead of it. For example, your avatar will auto-face the target on ability use, not on targeting. There may be other examples, but we need to be very cautious to avoid putting in things that could be exploited in the RVR game, however helpful they might be in PVE.
