I won't beat around the bush, no.
She's not a viable solo character, especially to deal with sub zero (since she probably loses that MU anyways). She has several really bad MUs and quite a few crippling weaknesses (poor anti-airs, bad wakeups, bad pokes, bad armour in general, bad jump attacks, poor range)
She does however have the following going for her:
- decent loop-able pressure (if you manage to touch them)
- good damage
- decent counter zoning
- relatively safe stuff
- safe 50/50s
- great walk speed
- good run speed
Full auto is far and away her best variation, though shotgun has some niche uses in certain match ups that it does better in than full auto. High tech is a joke in its current state, not even worth attempting to salvage.
