Time to go through my list i made over the past few weeks playing RoC and ReC and it is likely i forgot some things on the way.
Since GregTech removes vanilla Iron Ore, obtaining Sintered Tungsten is quite difficult. Instead, iron is obtained from Yellow/Brown Limonite Ore, Banded Iron Ore or Magnetite. So, how about also processing GT tungsten dust in the Blast Furnace and not only ReC Tungsten Flakes? Alternatively tungsten flakes as sideproduct in the extractor from Limonite?
Also: It is nice to have IC2 support, but once the limits come back into IC2, everything above 8192EU/t will lead to melted cables and explosions. So the EU mode of the Turbine Generator will be unusable. It is allready allmost impossible to store and distribute the power properply. I tried to implement the GT Powersystem myself today before asking so i could provide working code but after 4h trying to setup the devenv only to be stopped by the DragonApi because of wrong version.. So, how about implementing GTs IEnergyConnected and letting the Turbine generator outputting something like 1Amp per 2 kNm and 1V per 16rad/s? (~8192V @ 48Amp or 390kEU/t with an HP Turbine at full power)
The IC2 EU implenentation also seems to act up a bit. I have to replace machines sometimes until they connnect to IC2 cables.
And last: About the Lubricant use of the Turbines. I think they need too much lubricant. It is a good idea to still have a use for the canola farm but running multible turbines needs soo much lubricant that lag farms are necessary. How about being able to throttle the lubricant use of turbine while lowering the efficiency? Something like: Turbine speed^2 = Lubricant use and constant Steam usage. So half the power with the same Steam but 25% the lubricant use or 25% power but only 6.25% lubricant use. Its like that in reality too. Only running machinery close to its limit needs lots of lubricant. There is not even any need for so much power in the end, so why not material efficientcy instead of extreme power?
