I have been playing STO since the second weekend of closed beta. I have been a lifetime subscriber since before the early start perios before launch. What I have not been, is a hardcore endgame player. While I initially was very enthusiastic about playing a KDF captain, the realities imposed before launch ended that for not only myself, but many players. Most left and never came back. I was committed to the game, and my Fed fleet, so I stayed, though I dabbled with a couple of KDF captains.
I recently took control of our joint fleet KDF branch, and the KDF captain I have been playing recently took possession of a Vo'Quv carrier. While it is just the vanilla version, and I only have the EC versions of the BOP, I have to say, I will not play anything other than a Vo'Quv again. I have had to restructure my BO skills, my consoles, and my weapons choices, not to mention my playstyle. It is all worth it.
I was in love with the battlecruisers from the start, eschewing the BOP and the raptors. Nothing in Starfleet could compare with a battlecruiser, especially the Vor'cha class and it's variant, the Tor'khat. But now I am in love with that fat targ, the Vo'Quv, and I will be a carrier man until they pull the plug on the game.
I just brought the Karfi this afternoon, always been an Escort pilot prior to this, I can say in the 10 minutes I played on it this afternoon after spending a good half hour on set up , I dont think I will ever go back to an Escort with my klink, the thing is so damn versatile!
I picked one up today too, but I have to say that my survivability was crap. Like I said before, my build is not optimal, but on a foundry mission where the author said he couldn't play through without respawning, I managed to survive on my Vo'Quv. I will work on a build for the Kar'fi, I like how it turns, and I can probably get it setup to be more sturdy. I will have to take a look at my skill choices as well, see what I can tweak, I still have a gazillion respec tokens.
As an aside, man. I really regret some of my KDF ship purchases. Take a look at the Advanced Research Vessel Retrofit (fed, 2000 zen, tier 5). Then the Varanus (kdf, 2000 zen, tier 5).
Varanus is so much worse. Ok, it has one extra higher slot of science, but worse shields, worse hull, worse bonus power, and it's special console is of limited use even when it's working (which it usually doesn't.)
And let's not even get into those multi-mission fed ships.
