Was the game still fun when you could beat the game by taking ~5 planets via deep raiding, knowledge raid all of their neighbors, and beat the game at 9/9 with min AIP in 6 hours?
Sure, but I still think its a better game today, even though this was probably my favorite strat for a while.
Do fighters currently have settings where they shine?
Sure, but its a much more limited set than either cruisers or bombers.
I'm strongly in favor of increasing the role set of the fighter in some fashion, be it specific target kills, meat shielding, general killing or whatever. Of course, this gets us back to what should be their role, where we all seem to disagree. I think I'd be fine with a number of options here, I just think it should be expanded in some fashion.
