balance maybe? I played on a tekkit server for a long time, IC2's mass fabricator is the joke, you get the resources for a few HV solars (pretty easy when you use quarries/frame quarries) and you'll be creating tons of UU in no time, scrap or no scrap.The Gregtech Matterfabricator is a freaking joke. You literally spend HOURS just getting the resources to put it together. I thought it was going to be a faster machine than IC2's, boy was I wrong. It turns out it takes like 10x or 100x longer than the IC2 Massfab. I don't see why it is even in the game.
Easiest way to really get balance is make solar, wind, and water too hard to get in mass or implementing diminishing returns. To force people into the more complex and resource intensive energy methods of nuclear and advanced generator fuel use. Since as long as people can just wire up a massive array of the free energy systems than they will continue to abuse them to the bane of servers. Making advanced/compact solar a needed item to help mitigate it.
Personally I like a lot of what greg tech does since it reduces the need for uu matter with the addition of iridium ore. But said ore is a little too rare/hard to get due to being spread between the all mine able levels and one per 5 chunks. So the only way to effectively mine it is to fully strip mine the world for it or abuse mystcraft. As for finding it in the nether that is a bug that is fixed in latter gregtech versions which instead adds it to the end on rare floating islands/rocks.

Honestly if both of those were nerfed (the inclusion of compact/advanced solars and geothermal generators), I'd expect to see a lot of people then turn to Wind Mill towers which when built right are cheaper than you'd think, don't blot out the sun nearly as bad as a field of non-compact solar flowers would, and can viably match or even surpass the output of some mk1 Reactors in clear weather. Night doesn't effect them, storms only maximize their output, and I'm pretty sure you wind up with less packets sent than the equivalent solar fields which means less lag as well. Trying to keep just those two energy sources from trivializing EU generation is nothing more than making players trade 1 source of free energy for another.The problem with IC isn't the mass fab. The problem comes from compact solars that give 'free' energy and WAY too much of it.
Energy isn't free, it never is. You have to get it from somewhere. Solar energy is good 'free' energy but like IRL should take up a LOT of space. If that means a lot of lag then the IC authors should fix that but solar panels should always scale with the size of the farm because that's simply how solar farms work.
Seeing a mass fab running on compact solars and then simply disabling it is incredibly silly. They're designed to be run on nuclear reactors.
Free energy should be nerfed if you want to balance this. Both lava and solar. It's just plain wrong that just "lava" can generate energy. It's pretty silly that most engines that just take lava generate like double the energy that an engine on coal would generate while not even reuiring the input of water.
It can accept 8192 eu/t so you can put it in an eternal storm age with four lightning rods directly attached and it's pretty fast.
It was never intended to be faster though, it costs 100x the mass fab's cost to produce UU with scrap, and it requires scrap rather than leaving it optional. It's to balance it around Gregtech's crazy EU generation options without trivializing iridium, it probably shouldn't require iridium to craft though, that was a bit dumb imo.
The way I see it:
* Disable GregTech recipe changes if you don't play Minecraft much.
* Keep them enabled if you spend enough time on Minecraft to warrant the amount of work needed to get UU-matter.
Personally, I like it being crazy difficult to obtain UU-matter. Having a goal that is too easy to reach spoils the fun.
