Mentoring came with the previous update and is still being fine-tuned. With 3.0.4, mentors will be limited to 10 apprentices per character. Apprentices can be dismissed if a player is over the 10 limit and wants to add a new one. The dev team also announced a mentor/apprentice quest line that will give rewards to both. These quests can be accessed starting at level 10 and completed once per five levels beyond that.
Patch 3.0.4 will also include more improvements to questing. The quest tracker and find quest feature are slated to become more intuitive, and the automove ability has been expanded to allow the system to run players through multiple zones in one go. The devs examined the quest flow as well and adjusted it to make it smoother in certain areas.
The new server announced yesterday will be called Avilon and was created in response to a larger-than-expected influx of players onto the single North American shard. Players will not be able to transfer existing characters to Avilon, as the devs want to keep the server fresh and fair for those who roll there.
