While i get that someone might have intentionally removed these values to make hitting endgame a bit slower. this only leads to game breaking setups that will cause unneccesary stress on the server. Either ppl melt millions of buckets of Copper / Titanium and then use either dozens or even hundreds of auto-casters or Smeltery Casting Basins. Either method is very slow and only worth it if you go total ham on it. But may very well lead to unneccesary CPU usage. It also leads to unrealistically low FPS on those setups. To prevent this. just add a high-ish EMC value to Copper and Titanium blocks and make it harder that way to make them instead of forcing ppl to break the server. I'd say a value akin to Emerald blocks or even higher is about one of the highest EMC value for almost any regular block ingame. That would slow down progression without stressing the server.
I think this would help the server and players tremendously as at it's current state it can lead to incredible FPS and even TPS lags from setups to produce decent amounts of copper/titanium singularities.. they can really cause a lot of issues and having them get an EMC value would allow for some breathing time on the CPU.
Bumping this to the top of the list because im getting a feeling this has been overlooked. Would like this to be considered so i can stop breaking the server with my crazy setups for these blocks.
