I'll admit, I never really got on with the Onslaught. Too slow, too hard to turn, too easy to flank, and with all said and done just not enough firepower to justify the frustration of waiting to get into the action. The Conquest was faster and more maneuverable with the ability to bring almost as much firepower to bear, and the Paragon could outrange and outlast it.
With the new patch, the combination of Burn Drive and the Thermal Pulse Cannons + Mark IX Autocannons + Integrated Targeting Unit, this thing is terrifying. Absolutely capable of taking on entire fleets at range, and survivable enough to handily win a slugfest against a Conquest and two Dominators in the simulator.
And, with Burn Drive, there's less enemies running away, and less waiting to get into the action.
Kudos to Alex for making the ancient behemoth scary again!
