Not crazy at all. I'm not even pushing final coil and I have acc on my relic (not full acc). If you are looking to contribute to dps and dps checks, I don't see why it would be considered crazy at all. It is one of the few places we can actually get additional accuracy on something with mnd. Other SCH weapon options have healing stats but the relic can be used to fill in a dps gap that you can't fill with other options.
