Well, AI War players are nothing if not passionate

I think Keith has the right idea. Having two separate resources does add a little bit of strategy, in that some strategies can be hindered (partially, due to conversion ratios) by having unbalanced resource flows. No, it's not the strongest mechanic, but it's not broken either. It would be nice to find something stronger to replace it, but I haven't seen any suggestion that ranked high enough in the community to warrant that kind of change. Since we aren't dealing with a broken mechanic, it makes sense to give the discussion a bit more time to percolate and the developers and players to come up with a few other alternatives.

I have mixed feelings about CSGs. My first non-tutorial game, I was really frustrated when I got to the AI Homeworld and got completely destroyed by a Neinzul Melee Guard Post. I couldn't figure out why I couldn't even tell my ships to attack it...none of the immunities seemed to be a problem. Basically, I had little to no idea what the CSGs even did at that point. I was actually very surprised when I found out why I couldn't damage the Core Guard Posts, and wondered why the tutorials didn't even mention such a fundamental aspect of the game. So, I would disagree that they act as a guide for newer players--the tutorial does a good enough job of that, IMO.
That said, I play with CSGs on, in low AIP games. Why would I do that? Well, I see AI War as a sort of RTS puzzle. The enemy has built up massive defenses that I have to crack in order to succeed. But, I only want to take so many planets, because the AI is not very nice if I just start taking over the galaxy. CSGs are one more piece of that puzzle to me. How can I take planets in an efficient manner to:
- Keep the AI from destroying me in some humiliating way (ie low AIP...not that it prevents the AI from humbling me repeatedly )?
- Avoid deepstrike threat (get stepping stones to the AI Homeworld)?
- Destroy the AI's defenses (includes CSGs, among other things)?
- Acquire the technology I need to crack defenses (somewhat overlaps with CSGs)?
- Have enough resources (M, C, & E) to sustain a fleet (also somewhat overlaps with CSGs)?
Are CSGs the best mechanic since sliced bread? No. But, I haven't felt irked at them enough to shut them off either. And, quite frankly, I still haven't seen a mechanic that would do their job well, or even adequately (force the strategic capture of a few planets and limit the minimum AIP before finishing the AI Homeworlds). I don't think that's from lack of developers and players trying--it's just a difficult portion of the game to balance without making the game too difficult or too easy.

My 2.72 cents.
