I use W&R just to bother the peeps cos of the -100 nanoskill, but it surely could get a dmg and debuff boost for pvp.
For the tactics, I try to do the same, but usually, one of the few that run after you got root/stun/calm. So distraction works, but is quickly ended. It sure allowed me to win a couple of BS, but with real pvpers, such tactic is like... irrelevant. :/
Now running around full def with CH ready, I survive for a longer time, but this doesn't mean we have it easy. We are prolly the nerfest prof in pvp and I think it's time to allow us either do more dmg (but I consider this as less "doc"-like) or to get defenses.
On the zerg to kill a doc-comment: an undisciplined horde is needed to take down a doc, but two profs can without problem if the chair-keyboard interface is capable enough. And I consider that if any prof should survive zergs, it's doc. We are at most an annoyance anyways, where's our dd? I prefer FC ungmping my pvp dmg even more, bt let me survive 50 clammies zerging on me cos I'm doc.
But that's how I see the prof.
For the agent subject, well, I am pvmer, so not used to pvp tactics at all. But staying toe-to-toe to good agents who can CH themselves + stun and trigger some dmg proc higher than even all best doc dots combined + AS + higher normal dmg is a challenge. Too bad I dislike pvp that much, if it was a pvm mob (with slightly toned down dmg), I would have loved the challenge.
For the advy nemesis, yeah, it's an annoyance, but when you got zerged, it gets real hot for my poor doc bum. ^^
