I'm not disagreeing that you experienced what you experienced, but I find the exact opposite.
On both my Bonne'*, I upgraded to raybestos ceramics, and always intended to upgrade the rotors. But in both cases, I got so sick of the brake dust, I just put the ceramics on, thinking I would put the rotors on later.
The 97 went from 65k to 130k on the same set of pads, and stock rotors. Pad life was great, and the rotors never warped. And I drive like I was running from the law. (Hard stops from 85 MPH every morning on a really fun corner on the way to work.)
On my 2000, I have put on the same brand pads, and painted the calipers BRIGHT red. Looks good, IMHO, and have yet to see a problem. Seems as though I will get similar durability. I still intend on putting on slotted rotors, mostly for the look.
Sorry to hear about your trouble, but wanted to give my opinion of the ceramics.
