No, actually they are not. My 3 yellow dice may not generate much more successes than someone with raw ability, but I could potentially get three Triumphs. You cant do that with just four greens.
Again, the author is totally ignoring Despairs. Yeah, if you just want failures, a Red die is not that much more devastating than a purple. But, as we see in the Awesome Triumph and Despairs thread, getting a despair is way more interesting than just failing.
Could you point me to the awesome Triumphs and Despairs thread? I did some searches but apparently my search-fu is not good today.
