I prefer a game where every unit is equally viable. There is more all-round units and there is units for more specific cases, the winning player should use them in harmony constantly countering their opponent and introducing them to new threats. You should be able to sit behind your walls if you'd like or demolish your enemies with aggressive rushes, tech for few big units, or depend on numbers to achieve victory. Every strategy has their counter and key to victory is figuring out how to deal with each particular circumstance in the most efficient fashion. That is the game I want to play, that game is not "Supreme Commander: Forged Alliance" as it is.
Maybe you prefer a game with less strategic variety, that's okay, this mod is not for you.
I would like to add that sticking to the iterative progress that we've had over years, in this game and many others is probably for the best...
As to why many other games seem to use iterative balancing process (and I say seem because every game has gone through big changes before release)... I can name at least three reasons for that. Firstly most games are balanced better than FA out of the box so no big changes are required. Secondly most games don't have the resources for anything more than small changes past the release date. Thirdly game designers are extremely cautious about doing big changes after already shipping the game and for a good reason too, just look at FAF, every time someone suggests a change they get overwhelmed with flame. People don't want to relearn the game and fear it will just get worse from any change. It's acceptable to think this way, but don't imply it has something to do with the changes being "bad" - don't talk about shit you have no clue about - like Exotic_Retard said, you can't just skim through extensive patchnotes and give your so very "intelligent" opinion on them. Balance is not simple, don't treat it as such.
That being said there is something worth fighting for in this mod. It's an honest attempt at solving some of the underlying problems within FA balance. While Ithilis might not be able to communicate his ideas very eloquently, his work in this mod is admirable and truly better than any superficial "nerf this buff that" attempt at balance. This is a rework on the whole balance of the game in order to generate more fluid and diverse gameplay.
I've played a couple of games with this mod and I can't yet say a thing about the balance, it's a lot to take in and it will take time before people will adapt. One thing I do know is that it's taking the right direction, maybe one day it will become something truly beautiful and we can depart from the abomination we call FAF balance. And hey, if the mod really does suck incurably forevermore, there's still a lot that can be learned from it.
I don't particularly mind relearning game balance anyway, I actually rather enjoy the process.
