Kommander Sorscha: What to Do?

When looking at a Warcaster, there's a few things I'm looking for.  Accuracy buff, damage buff, speed buff, defense buff, damage output and debuffs.  These can come from spells, feats or ability's.  Debuffs are generally anything that has a negative effect on the enemy.  I would include a knockdown effect like Earthquake and Inhospitable Ground as debuffs.  The more of these categories that a caster covers, the better.  The broader the effect is, the better it is. 

So what can Sorscha do for her army?
She has three ways to indirectly increase the accuracy of her army, through her feat, two spells and the crit on Frostfang.  She can cast Boundless Charge on three models in a round, at the cost of not doing much else.  She can grant concealment to everyone within 12".  She has a Handcannon and a reach melee weapon at reasonable power.  Getting frozen will make models lose there next activation, if used correctly.  Sorscha covers a lot of the criteria that I'm looking for, some of it better than others.  What she is lacking is any kind of damage buffs, so I'm going to need to find models that already have high damage output or can increase their own damage.  On the plus side, nothing on her card calls for friendly faction models, so I can use any and all mercenary's that will work for Khador.

The hard part is what will Sorscha be doing during the game?  I see three roles that she can take.

1. Focus battery.  Just handing out focus to jacks and letting them do the heavy lifting.  Because she only has 6 focus and no battlegroup spells or abilities, I don't want to spam jacks.  I can take more if they need less focus because they do something for free or will be making limited attacks.
2. Super Solo.  In this role, Sorscha is running around killing things.  Charge, kill a few models and Wind Rush away lets me inflict damage and stay somewhat safe.  This can be a very risky way to run, because if something goes wrong, then it's game over.
3. Spell Slinger.  Casting spells like Freezing Grip and Tempest to lock down units or set them up for the army to kill.  Gives a bit more freedom and range, but is more focus intensive.  

In reality she will be doing a mix of each of these during the game.  It's best to keep them all in mind and use what will workout that turn.
