I bought it, nice little tank. I use it with my engineer toon and love it. Great DPS, shield mod isn't such a problem with maco xii and 1 field gen, 9.7k shield. 34500 hull translate to over 46k with my skills in space.
the 2 lt eng makes it great for tanking. I have 2 copy of epts running constantly, 1 aux to struc makes it tougher and 1 RSP to save my butt when shield gets low.
Commander tac and Lt commander tac bof gives me all I need in offensive powers.
Ensign sci may hurt a non engineer, but it doesn't bother me too much, slotted HE there.
Tried it last night and, in Cure elite, I soloed and tanked negvar and raptor on 2 cubes. In fact, 3 stfs and I didn't die once.
The console is nice and cooldown is low enough to be used often. Its only 12 sec but it acted pretty much like borg shield proc. Gave me the few sec to hit another buff before I died and even used it to help a teammate in trouble. He now officially want one of these. The console is truly universal, I can put it on any ship I want even shuttle.
To sum it up, love it, more tanky escort I own and firepower on par with most tiers 5 ship and 10 consoles is real nice.
One more ship in my collection
Jamal : Tactical space specialist. USS Bug Warrior and many others
E'Mc2 : Science Reman torp T'Varo, deadly annoyance
Kunmal: Tactical fed Klingon, ground specialist, USS Kanewaga
Ka -tet Tier 5 fleet fully completed Starbase and fleet property
Like the above player, I'm a fan of the steamrunner. The lack of Lt. Sci skills takes a little getting used to, but most non-Engineers could just toss in an Ensign Science Team to the slot and be just fine.
My one pet peeve with the ship is how dark the hull is. Seems like regardless of what light I'm in, it's always black or cast in shadow. Even Type 6 is too dark.
The Somraw, K'tinga, D'Kyr, D7, Kumari, Xindi carrier, Xindi escort, and the T'Varo are all older than the Constitution Refit and yet they are tier 5. The Constellation is made up primarily of Connie refit parts and it is tier 5, there is no logical reason whatsoever for the no tier 5/6 connie rule.
This is my new go-to ship for STFs... its got good damage output, great shields for an escort and if you run your EN Boffs like the OP says, it doesn't die!!! Well worth the $10... but not worth $25 so buy it now!
