It's not that hard ones you understand the breeding system. Volcano and flaming rock are in fact equal. They are even located in the same dificulty: So you are just unlucky in your case.

Only legend + legend can result an pure dragon and the chance is also really low. Pure is that hard to breed because he's located in dificulty 2 and when breeding two legend dragons they already have unlocked all dificulty 2 slots. So how higher you level them how more your chance will decrease. it's just simple math.

It's not always, breeding two of the same legend dragons together will do the following things:
 * It will not have an chance on other legend dragons, however because the two legend dragons are the same the parent will still be add to the array list because the duplication process.
 * Your chance on pure decrease, (server side action)

They made it that complex for an reason. I'm still thinking what process they use for that dragon. I first thought it was because of the opposite detection but I can't tell for sure.
