Issues i have with the order in which things are unlocked

I know that Kerbin has no industry that does not directly relate to aerospace development, but there are some technologies that are essentially the same thing, but where they are on the tree is totally arbitrary, as struts are are higher than yhe structural parts.

Surely if there is access to sort metalwork to make a latticework of struts, and struts are like that, but slightly easier to make. They re just long pieces of metal. if you have access the sort of facilities to make cryogenic fuel tanks, then you build a long piece of aluminum.

The same with decouplers, which are similar to SRBs, and I'm sure that it is quite easy to make a decoupler.

As much as logic goes, don't forget that the placement of parts on the nodes is to guide a player through the parts list, not necessarily following technological advances in the metal industry.

Oh, and if the MK.I pod has reaction wheels, why does the SAS come later?

My theory is that the capsule "SAS" is just the kerbal inside throwing himself around to push the capsule.

The pods have reaction wheels because they need reaction wheels. The idea that a spacecraft may be large enough to require more reaction wheels than the pod itself has, may be a little too far beyond the Kerbals' imagination at the start of the program.
