Dragon monks are okay,  i probably give off the impression that they are really horrible, but truth be told they arent that bad.  The major problems with the dragon style are:

1) Ae's: they have to many, and most of them are severly under powered and worthless (dragon breath, defensive ae, etc)
2) The mitigation penalty in offensive stance: Its way to severe and unjustified.  Theres no good reason why it needs to take 90% of dragon monks to 0% mitigation. 
3) They feel unfinished:  Stuff like dragon breath doing 2k dmg and sundragons corona being a damage shield seem under thought.  In reality theres no reason for a monk to have 7 ae, and for the most offensive monk to have a damage shield instead of a dmg buff.  That and each of the other 2 forms has an invulnerability. 

All things being said and done dragons dps is okay, its not where it should be and levels 15-49, they will probably be the highest dps tied with harmonious.  At 50 a well played drunken SHOULD top the list if EXCEPTIONALLY well geaed, where as a harmonious at 50 tends to take a lead over the AVERAGE dragon/drunken.

Once you start talking fully raid geared, its a different story.  This is 1% of the population and as such i dont think it should be adjusted but its funny to see.  Drunken>dragon> harmonious.    With full raid gear and raid buffs, Drunken monks will break 5-6k dps, which is more then rogues.  this is 100% due to refresh haste and their lvl 50 finisher.  4x thousand fists every 30 seconds is rediculously over powered.  Add in armor proc from fist of celerity and and 2 self dps buffs and drunkens really shine.   The thing is their regular attacks do squat for dps, and its not till 50 with max gear that they start to overtake the other 2 styles.... so 49 levels of being lowest dps seems fair. 

All things said and done, i think all 3 styles should have invuln buff.  All 3 styles should have at least 3 hits in the thousand fist chain (and drunkens get the 4th at 50).  This would raise the bar quite a bit for harmonious and dragon and probably let them over take drunken.

if ur almost lvl 40 in dragon style i would say stick with it go to lvl 50 with it run apw for a little while get the feel of that type of contnet with a dragon style.

then switch styles and test n tune diff styles then u will be able to see how the other styles work

i did and i like switching styles it was cool to see what the other styles do ect and im currently drunken and yes im comparing it to dragon.

so far im happy with it its a change from the like fuji said 7 aoe dps to a more evasive class with little more abilty for the grp

oh n p.s..... now i just heard this thru the grape vine ..well actually  it was written on the wall at the khal tavern restroom,

but the guys at the harmonious dojo wear girly pants

any monks on seradon server wanna /duel  no not pvp i understand the philosphy behind that for some peeps i just need get my monk arse kicked few times get my rythem up to par ect.

*shrug* I do great damage as drunken, have tried harmonious, and I still say I did more damage as Dragon.  Dragon also  has the best chains by far with enraged, no one cares about drunken's and harm's solo chains in raids. I switched due to needing a perfect dodge ability for corpse dragging, getting to summoning room as dragon is a pain  .

I wouldn't mind having a dragon monk in my raid again, and if our monks would just stop taking "breaks from the game" I could have one maybe.

Well ... i switched from Dragon to Harmo some weeks ago after a long time of refusing and holding onto the once chosen class. Have to say i didn't regret up to now. With exactly same gear and skills i can solo much easier (did all 4 Graystone Blessings solo) and the raidgroup i'm in surely appreciates the Debuffs more than any AE of my former Dragonstyle.
