WildStar’s next update (1.6.2) will introduce several new cross faction features, giving rival factions a chance to team up against Laveka the Dark-Hearted and her minions in the second half of the Redmoon Terror raid.
Granted, this isn’t the only reason for the two factions to team up, as Dominion and Exile players will be able to run nearly any type of content together. This includes Veteran Dungeons and all raid zones — although Adventures and World Story instances remain single faction only.
In addition to giving players more opportunities to fill their groups in dungeons and raids, the update also implements social features designed to improve cross-faction play — allowing players to have cross-faction circles, neighbors, and friends.
A full breakdown of the new features can be found on the official post on the WildStar site.
