Well I guess those questions were too stupid

I noticed that I can't equip some items being sold at the broker - mostly because of equipment status. (I am at 29% and I can't equip a lvl 27 item). I was just wondering how that gets calculated.

a) How exactly do item level work and what are they linked to? What do I have to look for in order to know if I can equip and use a weapon or armor piece?
An item's stats is tied to its item level and rarity. A level 30 rare weapon (yellow) definately will have better stats than a lvl30 uncommon (blue) but lesser than a lvl30 heroic (orange).  For monks, it's better to look for +dex, +str, or at least +hp gear.

b) How do I compare weapons and what is the difference between calculating 2h dps and wielding two weapons with different dps.
Check the main hand and off hand dmg when unarmed or equiping knuckles, and add the damage numbers together and compare that number to ur 2H dps.

c) How does the weapon skill directly influence my fights? Besides the mentioned 10% add at max do I for example miss about 50% if they skill is half maxed? I am trying to keep as many weapon skills as possible up - you never know if they actually all of a sudden decide to give as a weapon that is worthwhile and uber!
Besides it's just looks cool if I am fighting with a sword for kicks
Weapon Archtype skills (2H blunt, 2H slash, Hand-to-hand, etc) determine ur accuracy. Maxed skill means 95% accuracy when fighting even con.  U can divide this number by 10 and the resulting figure can be used to guessitimate what level mobs u can expect to have 95% accuracy on.  For example, if your 2H slash skill is 200, then u can hit lvl20 mobs w/ 95% accuracy.

d) does Item durability influence dps and/or armor bonus. Say if my weapon is not at 100% will it not do it's full damage or is it just not working at all if it's at 0% (or both).
I'm not too sure on this... never actually checked lol. I'm sure when dur reaches 0% the item no longer have any effect until u repair it, but i'm not sure if it works at 1%.

e) about the two different Targets: I haven't really grouped yet but do you always have both active the defensive one and the offensive one, or do you have to switch accordingly?
You can have an offensive target AND a defensive target at the same time.  Off. target is the one u do damage towards, and def. target is the one u use rescue skills on.

A. Item level apposed to your level as well as item quality (green,blue,yellow,red) effect how much expertise cost it is.  The better quality higher level weapon will cost more expertise then an equal level weapon.  As you level up the item expertise requirement will go down on it. You cannot equip any single item that has a 20% or more expertise requirement.

B. I never use custom ui's, because anytime the devs change something the UI's get messed all up.  But the numbers from them are probably the same numbers you can already see on your character sheet

E. you can assist a target by making them your defensive target.  You then just push "F" and you will get there target

Item level also determines how fast an item loses durability when equipped and fighting mobs.  I have found out that if you equip an item more than 10 levels higher than you are, it loses durability FAST! Like, fight 10 mobs and it already broke down to 0%.   Equipment expertise cost only determines if u can equip the item YET - anything over 20% is unequipable, and the number decreases by 3% for each character level you gain.

All in all, I always aim for items 8 or 9 levels above me if i can afford them.

On assisting ur defensive target: just press F and you'll assist him.  No macro needed.

Google ParseThis, it has a VG plug in and while its not perfect helps me out quite a bit.

As far as stances go.. you should have gotten a new small UI window that has 3 round buttons in it.  those are your 3 different stances.

Vgparser has no support for any class other than rogues atm(because that's what I play). I am in the process of adding support for other classes as I get log samples. One thing I recomend when making a log is to setup a seperate window for logging just your attacks and autolog it. Use that log with vgparser. It cuts down on the size of the logs and also there are too many attacks that vg puts in the logs that are not attributed to a specific toon. So if you are only logging your own damage then all damage is yours. It makes it a bit easier to be accurate.

Also if you could let me know exactly what is not working I can try to help you out or make bug fixes if necessary!!
