Hmm, not sure whether I agree more with Distrurbance or Talan...
I haven't played a high level Doc, mine is still level 100, whilst Jaegerin dinged 210 last night - must update signature!
I've seen 215+ Docs soloing some pretty awesome mobs that at 209 I wouldn't think about touching
Saying that, I've seen adventurers soloing similar mobs and I've seen a lot of doctors on reclaim lately... The defensive abilities of the Adventurer are fantastic, and I think a Doc and Adventurer are an unstoppable duo at most levels! Out hunting patterns the other night, the only thing(s) that stopped us were Anansi's Right Hand, 4 Anansi Guardians, 2 Eremites and a 2nd Boss mob, can't remember the name all aggroing us together. When you are being hit for 40k plus a second, even BioCocoon and CH don't help
It will definitely be interesting to see what Jaegerin can solo later on - she can do SL solo missions with ~240 mobs in it now, and she has soloed 250+ Alien mobs in the ship after the rest of the raid chickened out because the doctor had to log out after the general...
My guess is that the Adv will kill them faster and with a Doc the mobs will die of boredom As long as the mobs aren't hitting the doctor for more HP than they have, per hit, I can't see the doctors having any real problems. The Adventurer needs to be a little more circumspect, they can't heal that much (the SL heals are excrutiatingly slow and can't match a Doctor for the amount per heal that gets healed), they have to rely more on their defences to minimise the incoming damage... I would say it is going to be a close call between them. But when the defences are down, I would probably give the Doc the win by a nose...
