Point for point you benefit more from int then from dex for a few reasons.

The main reason is int adds a flat dmg to each hit via secrets (yes its intended, we whined about it forever, so what ended up happening was 2 things. First, was skils were scaled to average monk int at 50... meaning to get our skill to do the said 600 dmg a hit we needed 200 int not 700.  Secondly, int has a larger effect on our spell dmg rating then it does on other classes.  So going from 200 int to 400 int at 50 increases our dmg from 600 a hit to 900 a hit, while that would only take a caster to about 700. 

Secondly the bonus from dex is very small in the grand scheme of things.  900 dex at 50 is what you need to cap the crits from dex.  Heres the catch, overall crit rate is caped at 40-50% so if your dual wielding (7.5%)  have 450 dex (10% crit) and have a few pieces of lucent gear ( about 1-2% a piece) your already at 25-30% crit.   If your a harmonious your at 40%.   If your ful apw geared your at 40%. 

Crit and dmg are amazing on t5 gear IF your are just dpsing, just remember if your gonna pull in APW youll want to trade the crit gear out and get HP gear.

I must admit i'm still not convinced by this 40% crit cap.

Are you sure that it isn't "40% cap from gear" and stance/buffs work separately/stack?
I just counted up all my gear/dex/stance and it came to a total of 82% crit unbuffed.
That means in tiger or crane stance i have the exact same crit chance and there is no point using the tiger stance.

However then i notice this: In tiger stance, crescent kick & ashen hand are essentially guaranteed auto-crits, not once ever have they failed to crit (except for misses), in crane stance they do fail albeit not very often but still they do.
Plz don't say i am talking SNARF or it is a placebo or something - try it yourself.

Also the stance is 30% crit which i assume means vs lvl 50?
So against the lvl 53s in APW it would scale down to what..something like 20-25%?

Not sure exactly of the numbers...but due to scaling wouldn't that mean you actually need closer to 50% crit to have the cap vs lvl 53?

Maybe i have got something wrong - Just some thoughts anyway 

Ok cool,
one other thing i was wondering about was secret of flame/ice crits.

Does harmonious tiger stance affect them too?
Seems like it would have a huge affect on them if so.
80% of gear is just "melee crit" so harmonious would be doing loads more damage from secrets than any other form right?

For instance a drunken monk unbuffed would be 5-10% spell crit, harmonious 35-40%

 

Hmm, tried respec'ing atrributes last night at 3 different trainers and everytime i hit the retrain button (and the "are you sure" button as well) it does not give the points back, it leaves them there. is this a known bug? I relogged and was still unable to respec.

Yeah prior to today's patch some trainers at different locations worked and others were broken.  Similar reports on other forums.  People had to hunt around and find trainers that weren't broken.

Good point Simon about level 53 scaling variations.  I'm not perfectly sure what the "cap vs. level 53" is for melee crits.  That would be a damn good question to see how much sense it makes (if any) to shoot past 40% crit for APW.  For example if you're at 40% naturall would the boost from buffs be enough?  (I'm guessing probably but its hard to say.)  Would be good to get a dev comment on that.  Maybe the rogues know?  (they tend to be a little parse obsessed)  

I would imagine the easiest way to verify how fighting a level 53 adjusts things is to simply use AA while the rest of the group/raid wails away for a bit.  See how things line up etc.  And yeah fuj is spot on, every melee class I've played has at least 1or2 skills with inflated crit chance, some say so in the tool tip, others you note from use.

Ahh yes, sorry. Recently returned to the game so catching up on everything is proving a difficult challenge. Bugs still abound, constant crashes the norm(Vista user w/ nvidia card ftl i guess). But the game does seem to have gotten better, secrets not on 2minute timers, our dps buff is 1hour on cast too(don't remember the jin cost being that extreme but still worth it for the 1h timer). The only thing that i think is really bugging me lately is the skill sets on the main page here are out of date. It doesn't look like the skill have been updated since release(and the forum stickies i've seen don't give good descriptions of each ability and any changes they may have undergone since release or what they do now for that matter either).
