Can either the "nerf" or the "leave it the way it is" states be modded? If so, why aren't we doing that instead of changing gameplay?
Although I admire the idealism, there are three problems with that. First which-ever group is the "mod" group is going to have a lot of practical issues coordinating the use of the mod. Secondly, it's harder to standardize the quality and support for a modded version than an official versions. Finally, it's not a good idea to split the community up between different versions of the game, as that makes it harder to find a match and leads to alienation.
The problem with carriers is less an issue of tweaking numbers, and more an underlying gameplay issue that people dislike. The issue that many of these people bring up isn't that strike craft can't be beaten, but rather that they don't like the effects of their unmatched mobility and firepower on gameplay. However, this is the kind of thing that gets changed in an expansion pack that brings new content and dynamics to the game, not a balance tweaking patch.
