I like the J'HEC I have on my Engineer captain, quite tanky, even with a Tac in the Lt. Universal (meaning only 1x Sci Ensign how I run it). I like it better than the Armitage, Steamrunner, and Breen Warship I had previously on that character (though I miss being able to toss out Gravity Wells in the Breen). It can shrug off things that'd have me hitting Miracle Worker on an Armitage. 2 base turnrate lower than an Armitage, but still very capable of getting things in it's 45 degree arc to rip into with it's DHCs in PvE.
I'm running Elite Scorpions on mine, and it should be able to slot any fed pets besides the Atrox's Stalkers.
The console is pretty nice, giving a boost to all your team's damage as well as getting them out of tractors and holds.
