The first change is that Donatra doesn't have near-instagib Torpedo Spreads and immensily powerful cannons anymore, which makes the fight fairer and less reliant on kiting her.
More important though is that her AI has been redone completely. She's more aggressive now, faster, and cloaks more intelligently now.
NX-91701 USS Gombe Stream has gotten a refit recently, now using plasma weaponry instead of traditional phasers. I don't know if the fact I'm not using phasers or that I'm proving Janeway right makes me feel dirtier.
Graviton Beam is still used to great effect. Knocked Donatra six kilometers backwards with it here.
This is the best thing about the fight: Donatra now uses the Thalaron Pulse Cannon with precision, always placing at least one player dead-center of the killzone. Makes for a nice deal of tension to hope you'll have Evasive Maneuvers in time to avoid certain destruction.
You didn't have close calls like these in the old version. This is much more fun than kiting unavoidable death torps.
The Scimitar is getting hammered to space scrap, and the new arsenal of the Gombe Stream is proving more and more effective.
Thar she blows! Overall, this in conjunction with Hive Onslaught Space Elite leave me very excited about the upcoming redux of Crystalline Entity instance.
Obligatory bridge shot. Should probably figure out something profound and wise to say as befits a Starfleet Captain.
