Campbell explains that warbands are essentially rare enemies taken up to the next level. Instead of just finding the occasional notable spawn, you'll see groups of enemies roaming the world, marked on your map and just waiting for you to ride off and challenge them. These bands will vary in size, with some requiring only a single player and some potentially requiring a full raid to defeat. The bands are also subject to a new "open tapping" system, which allows players to work together and receive rewards without being in a full group and encourages players to challenge these bands without worrying about competition.
