As the self appointed dual Guru [lols] here's some tips for you.
DEX: Main AP + Dodge. Medium Priority.
STR: Secondary AP + Def + Max HP [also weight carry] Medium Priority.
CHA: Buff increase + Debuff increase + Healing increase. Medium Priority.
[by medium priority I mean they should all be close in value. if you have 130 dex at your level, having 100-130 str and 100-130 cha is recommended]
Secondary considerations.
SEN: Critical Rate + 1/10 AP [10sen = 1 ap before passives]
If you're doing PvM this is a potent stat, if you get a 50% critical rate, you're effectively increased your DPS by 25%. Easily done in PvM.
Attack Speed: In conjunction with Shattering Blows and a modest CHA build, you can stack def pierce, def downs and pierce defense items to get an unholy amount of defense mitigation. 1 build I'd worked out had the following
40% + 1009 def pierce. [Def pierce passives + Def pierce set + gems]
35% + 1400 def down.
This turns even knights into paper bags. If you have the critical advantage + a citrine, using bloody assault [340% + 160] with 80% critical damage. You're going to damage cap on any class [with exception to a blocked hit].
Accuracy: Duals have modest accuracy, in PvM this isn't an issue. For PvP you might want an accuracy set.
I'd recommend you have approximately 2k accuracy [full buffed]. You can get this without the accuracy passives if you use an Exalted set with 20con / 75 accu sub-stats. This set is almost entirely geared towards fighting Katars / Duals. Scouts have near laughable dodge in most cases unless they've build for it and invested many gear slots / subs to dodge [most won't].
And Lastly, MoveSpeed:
Raiders in general have good movespeed. However nothing is more frustrating then being a melee and getting kited constantly by a ranged char. Give yourself some movespeed + make sure you get Enfeeblement. It doesn't last long, but it can work as a gap closer. Also, if your build allows for stealth, it can double as a get out / gap closer. Same can also be said for mystic knife.
Cheers, and goodluck.
