Yikes, I go to sleep and all this happens.

Anyway, I'll be tweaking Keshik (Or Kheshig, to stick with the traditional spelling) when I get back from work. Main thing would be to drop his stealth specialization and replace it with gadgetry, thereby implying that he's not really all that patient enough to go 'full stealth' on a mission, if I may use video game terminology here. He'll make his way to generator rooms or server farms unnoticed, but after he gets an EMP in place, he'll light the place up.

I'll also guess that just because he's not an expert or master at something doesn't mean that he's completely useless at it.
