Well to be fair, only g4/g5/mods are having insane reqs, g2 and g3 are not really complex, or, a chain of Apex runs checking shops in a system with a number of stations on Thursday while doing something else isn't really a big thing. Idk for sure, but from my feeling a rather big number of stations do spawn modded equipment (seen up to 3, and that's in each section) at reset, maybe even all of them, question is if you're the first person checking that shop. In fact i guess at these times not much ppl even take unmodded g2 and even g3 due a wish for mods too.
The only one real need of g5 is ground pvp. Also for completion sake, ok, but the fact that completion is expensive is excusable. I did wipe with my g3 gear while clearing a big military base (i guess that'd be the hardest thing, CZs seem much easier), but it is possible in g3. I did return there later with another mission and made it. P
Looking to make modded g4 and g5 is a little heavy though i agree. It just looks like some either not-counted-well (bugged basically) stuff, either some artificial walls from the devs. Like want a g3 Dom? Sure, check the shops, bet you'll have it tonight, if not, try next week. And then you hit Opinion polls point, those you'll do by Xmas.
