I guess I don't see the need to or fascination with seeing these three ships played. There are plenty of other ships to choose from and all races have ships no one plays (for the various, differing reasons). It seems like these three always seem to get the press, though.
Certainly drones and drone defense can be deemed as root causes of their lack of D2 viability. If you are Fed player and have other choices available to you, you will, of course, choose them because you have more tactical flexibility.
As was mentioned, the drawback (in some Klingon players' eyes) to our carriers is that aside from the C7V and B10V (which we gladly fly), our carriers lack drone racks. Personally, I feel the problem with them is two-fold--- lack of drone racks and less than desirable (compared to other fighter races) fighters. We've gotten by with steering clear of our carriers until we can get a C7V, but this problem is probably the main reason you don't know any great Klingon carrier jocks.
One is always going to gravitate to the ship that gives you the most options.
The BCE, CAI and Miranda, in terms of the dyna, are understandably less desirable. What wrong with that?
I guess it's your shiplist and campaign, Dizzy. If you want to soup 'em up, have at it...heheh.
