Little off topic but I found solo'ing my scout incredibly difficult at first.. Until I figured it out. It's all about having a good pattern of abilities to use until you can stun the mob again. My usual round went something like:
Backshot
Cheap Shot (stun and stop fighting)
Stalk (quick walk around to the back of the mob)
Shadowblade
Bleed
Pierce
Impale
By then the cheap shot timer was usually up again and I could do another stealth or positional attack. I'll admit that I didn't get my scout very far so I don't know what it was like at higher levels but I was killing solo orange mobs and green^^ group mobs at lvl 16 (sometimes blue^^ but that was pretty risky and generally not worth it).
Soloing with a scout is definitly an art form. If everything goes right, the fights are short and sweet. If something goes wrong, start preparing to retrieve your shard.
