I might upgrade it at some point. I don't have enough EC or Zen for that yet, though. (2.5 million EC in the bank, about 300 Zen)
Also, I am still seriously digging my Mirror Vo'Quv. I wanted the Obelisk Carrier when I first played it in Sphere of Influence, and considered the Vo'Quv a consolation prize of sorts, but after going back and re-playing Sphere of Influence, the Obelisk carrier is only very slightly better. Looking at the STO Wiki, the Obelisk has 1500 more base hull points, one extra Bridge Crew slot but one less rank on the Science Bridge slot, Bonus +10 Shield/+10 Aux instead of +5 Weapons/+10 Aux, and different specialized Hangar pets, Obelisk Swarmers vs. B'Rotlh Bird-of-Prey. But they have the same Shield multiplier, the same Impulse Speed multiplier, the same Inertia, the same Console slots, the same Device slots, the same Weapon slots, and the same crappy Turn Radius of 5. The biggest difference is the Warriors Way ability you only have in the Sphere of Influence mission which makes the Obelisk Carrier seem a lot more powerful than it normally is. So my "consolation prize" is not bad at all, and I'm not in as much of a rush to replace it. (The Advanced Obelisk Carrier is a definite improvement over both, but I have no idea how to get that on the Console version. It's not in the Lobi store where it's supposed to be. Maybe it's not on the Console version at all)
The only T6 I really want at the moment is the Herald Vonph Dreadnought Carrier, but that is absurdly priced on the Exchange - 500+ million ECs - and there's no other way to get it at the moment. I'll just keep saving ECs and Zen for the time being. Alternatively, I may look into the price of the Quas Cruiser or the Durgath Battlecruiser on the Exchange, too. (I remember checking that everything with "Carrier" in the name was ungodly expensive, but I'd forgotten that not every Hangar-capable ship has "Carrier" in the name, including those two) Edit: checked the Exchange, and the Quas is less than the Vonph, but still way out of my price range, running tens of millions. The Durgath isn't on there at all.
STO has been the first game I've enjoyed this much since CoH went down.
