Yes, but the prince can use system jammer, autothrusters, had 3 agility dice, and enough post dial movement options to exploit the donut hole.
He will be fine.
First, it is more of a "C" than a doughnut hole, as they can still fire primary weapons. Second, he will be hard pressed to be in all of the TLT holes. The odds are he will still be in range of 2 or 3 TLTs. Yes, Autothrusters will serve him well. Sensor Jammer feels like a waste on him against other lists, but would help against TLT spam. Glitterstim would help him close range. However, they do negate his ability, which is the reason I normally pick him over Guri.
