That is also true, im looking on the forums at positive and negative things to see what people are doing with ToC, for example one person said they only work on lost sectors, patrols, and region chests. Once I get a bit more information I'm going to do a test and crunch the numbers to see what is up with them. It very well may be that people expect an exotic like you said, but that doesn't seem to be the case for some people who get "no blaming exotics over 8 blaming hours with three of coins!" Though from the tone of that it could for sure be exaggeration.
