I'm just going to go ahead here and say NO.
Yes, making Toxic Waste actually profitable as a regular commodity would be really nice, and fixing Toxic Waste mining and making it actually viable would be even better, but I've given up on that.
Nobody cares about Toxic Waste except us, so I don't expect that to ever be fixed. AD told me in [checking] late October '13 that it "wasn't a priority" to fix Toxic Waste, and I doubt it ever will be.
So ALG has essentially given up on what's supposed to be our main RP commodity, and because of that we can focus on scrap metal, our second most important RP commodity, which incidentally has also been broken forever.
And as much as I like the idea of some waste-related activity being profitable, I don't want it to be at the cost of scrap metal, because ALG lore going back to vanilla declares scrap as a major part of our business. It is a type of waste after all, and we collect that sort of thing.
I'd much rather have scrap metal properly balanced as a mining commodity than having some quick fix done to Toxic Waste which, looking at other quick "fixes", including but not limited to this latest balancing disaster with scrap, would likely do more harm than good.
