In SOD, about the time I hit FOS, and all the indoor dungeons I wanted to do I decided the monk was the way to go for pulling. It has worked brilliantly and he has replaced my mage in my 3 box with mercs or friends group.
My monk has about 700 AAs, and almost all were focused to pulling or defensive. I just now am starting to branch out to get some DPS AAs and offensive power. I intend to get a parser soon and see how he is doing on dps as I put more AAs in to that.
Currently he is in a mix of SOD group gear, mostly T4, 1 T3 (stupid hat essence won't drop) and 2-3 T5. Using high maul of ?? from Tosk, and dire Cestie (main hand).
I have had him 'emergency tank' up to Korafax trash so far. He tanked Beguiler Chandra from about 18%, using delay death skill and at the end impenetrable. Wasn't pretty but he got the job done! I have actually been quite impressed with his abilities this expac, so was surprised to see your discussion of the state of monk.
I really like his pulling skills. I'd like to see Imitate death on a bit faster recycle, and it's a bit annoying to be lieing down waiting for agro to clear where I know a bard just has to /fade a mob off.
I have a bard friend who groups with me quite often, and there are certain pulls that we always put the monk on. Beguiler Chandra being one of them because monk has shown to be a better rampage tank than the bard so far. Mend has been brilliant for this as well as delay death. I haven't used impenetrable on rampage yet, because I wasn't sure if that pushed him off of rampage tank or not?
Stuff that I wanted to talk to you about, in complete randomivity.
Grappling strike: Been having troubles with the enrage/walk away but can't be snared mobs in Korafax( caught me off guard the first time. hehe.) so I bought this AA. Wasn't a lot of use to stop them, but MAN! was it brilliant to help with positioning when my merc tank decided to jump in too early in tight spaces. Any other uses for this that I might have missed? This one alone made it worth while, and wish I had bought it long ago!
As I had said, I have bought almost exclusively defensive or pulling type AAs. Anything that made him tougher to kill, or made the job easier to pull was priority one. The only defensive AA I haven't bought is staff block, because I don't have a good 2hb so I use 2 1h weapons.
What would be the most recommended AAs MUST HAVE types for monk on the offensive side? Just kind of an order of preference thing. Decided I'd start with the 18 lvls of extra strikes from main hand, but quite willing to refocus if there are better bang for the AA buck.

NOTE:I can't access the monk boards from work, and I tend not to surf much in the evening as I like to spend what time I have for EQ on playing EQ.
Peace
