Nah, my changing of the mechanic was mainly because it was an oversight in the operation of the machines - having the Smelter mechanically dominate the Pulverizer wasn't good internal balance. I had figured that out shortly after adding it, and even then, the only real issue is that there was a mod that added a ludicrously rare metal. Believe it or not, I hadn't even heard of Etho til this thread and in general I just don't follow any of the big Youtubers/streamers at all. Any major exploit or imbalance that I fix is basically because I feel it needs fixing or someone directly informs me.
Speaking of ludicrously rare metals, are Shiny Ingots part of TE? If so, what are they planned to be used for?
