MATHOSIA

 * Streamlined quest flow to get new characters into Freemarch more quickly.

DUNGEONS AND RAIDS

CONQUEST

 * Conquest queuing has officially changed - although some of these effects were appearing early on Live! While you can still select a team via the Join buttons, this is now treated as a preference and not an absolute. If your requested team is currently full, while another team has room, you will now join that team rather than remaining queued. If the entire match is full, you will remain queued until a space opens.

 * Screaming Blade is now properly statted for tanking.
 * Empyreal Vanquisher's Dagger is now Unique-Equip to match the other paths of its upgrade tree.
