I just got a Kratus dragon from breeding 2 lv 4 pure dragons. It is a hybrid, but only a category 4. Any one use it in Combat? While I'm at it, which category 5 hybrid dragons seem to be the strongest or have the best attack moves? I have a dark at Lv. 24, but the metal and flame seem to be the better ones to me.
