The PvP titled doc is going to be very scarce.
Cz answered a few questions for aovault recently including:Since the damage output from docs will always lag that of other profs, duelling will continue to be the only source of PvP titles for docs. And, if you do combat teamed, you will only lose title points.from Developer Q&A #1
Q: With the NW came a lot of mass/team pvp, can you please explain how pvp titles work in a team fight? Who is getting the title increase? The one who did the most damage, the one who got the killing blow or is it split amongst all the team members? - Brancaleone
A: The PvP ranking in team PvP is handled exactly like in solo PvP; the kill goes to the one dealing the most damage on the victim, and points are gained and lost regardless of being in a team, i.e. ranking points (gained or lost) are not split among the team members.
