I'm just listing the most efficient ways to duo level, it's not my job to also make friends for you.

Please tell me while duo leveling with a shaman where you will ever need to mez a mob before level 55. In the leveling examples I listed from 39-55 neither of those camps require mez ever, and there are no camps that will provide more efficient exp. I'm especially interested in hearing when you think mez will come into play at HHK nobles or spirocs.

Widan,

I don't doubt that your shaman/ench duo, that has spent the last 20 or so levels in
two zones (HHK and TD), is EXTREMELY efficient by now and can easily get by
without a mez that lasts longer than 12 seconds, but the purpose of this thread is to
discuss the best duo, and in my humble opinion, one of the criteria should be that the
duo can be effective in almost ANY zone.

Now, you take your uber shaman/ench duo deep into Karnor's or Sebilis and see how
well it works there with just a 12-second mezz. And, if perchance, you make
a small mistake somewhere along the line and your little duo wipes, then you
get to spend LOTS of time either making up for that yellow of exp you just lost
or finding a cleric to rez you. With a cleric partner, this downtime is minimized,
unless you've got friends/guildies who will drop what they are doing to come
and rez you.

I don't disagree with a lot of what you are saying. I think a chanter + any healer
is a great duo and that the best duo ultimately depends on the players behind them.
I just don't think you need to put down everything I say to try to get your point
across...

Based on personal experience...
 

I'd vote Shaman+Monk, with Shaman+Enchanter as a second best. Note, I haven't tried a great number of duos, but from what I have tried, Shaman+Monk worked best. Remember though, it's also important to factor in who your playing with.

Leveling 39-55 at precisely two camps would make me want to stab a pencil through my eye before ever logging on to EQ again.
