On average, you're better off breeding with 4 elements - the other dragons produced from Cold Dragon + Dark Dragon have long failure times, and an average failure time of 11.8 hours if you look athttp://www.2084.org/dragonvale/breeding-sandbox/

The average failure time for the 4 element combos gets down to 9.8 hours, but if you're unlucky you can get stuck with several very long failures in a row.

Some dragons just seem to take forever (it's all luck); I spent most of the BeB event with both islands using level 19/20 dragons to get a second Arbor, and it took more than 2 weeks.
