The reason I'm not running a backstabbing rogue is mostly because the backstab hit area is ridiculously small and it gets tedious to position yourself correctly.
To combat this problem a bit I suggest as many AP's per turn as possible so you get more bang for your buck (more stabs per time moved). Ie: the Glass Cannon talent and good speed.
It really depends on your party composition though. I would personally go with:
- 1 Lone Wolf Backstabber as the main damage dealer with 2 mages who crowdcontrol and buff.
The great thing about these crowdcontrol/buff spells is that you don't need high int for it. Just enough to get 100% chance to apply and for gear requirements. This leaves you with more speed so you can do more per turn and just let your rogue do all the killing. When something goes wrong, stealth/invis spell and regroup.
Oh and btw, don't bother with the "rogue" skills (lockpicking or pickpocket are fairly pointless)
