I've got HW, but I never finished it. It got boring after U get Missile Destroyers.
In fact, that's a pretty major gripe I've got against the game. They give you no shortage of crap to blind-side small stuff with (Grav-well gens, missile destroyers, ect.) but the only thing that they give you to get cap-ships with are... bigger capships (and salvage corvettes, if you can get them to live long enough that is

).
I actually thought the 'paper-rock-sissors' thing they had going was pretty cool (corvettes beat fighters, cap-ships beat corvettes, fighters beat cap-ships), it made you think about your force organization and composition a lot more. Once you get m.destroyers there is no thought involved, except whether you should build a h.cruiser before or after you max out your beam frigates.
I also don't like the fact that the assault frigate is completely useless either...
