The problem: They take 4-6 times as long to run, but pay the same as the normal tasks. So if you are concerned about credits, this is a problem. Also, these TRC tasks use the same app, so you can't avoid them via app selection.
I am trying hard to be the first to 100M, so I can't just stay away until this gets resolved. But if you are not worried about things like that, and you are worried about credits, then stay away for now.
