All you really need to do is decide whether you want this to be a striker or defender. I would lean more toward striker simply because of the lackluster armor and hitpoints, but you could push it back toward defender by tweaking those.
If you want it to be a striker give it a "Sneak Attack" analog and you're golden (Jump anyone?).
If you want it to be a defender raise the armor profs, raise the hps, lose acrobatics from the skills and give it a marking ability and you're golden.
The class has some control-y aspects, but that's okay, the Rogue and the Fighter both have some secondary control function, so it's no big deal.
