I do think that the other dragons are useful even today. Because despite what people here say, all the dragons can expand on turn 1 without awe. As long as you only expands towards type-less provinces that is. Dark vines will do you in no mater what kind of awe you got. This is not my musing. I have tested this in SP dozens of times and done it successfully in MP twice as well. In none of these tests the dragon died or was defeated.

As for the other dragons, the blue one is the weakest I think. Though it have AOE 5, not 3. The fire dragon is highly useful because he is one of few thing in the current CBM that can summon Zmeys cheaply and quickly. He only needs F4 if he can get the death/fire booster. F5 otherwise. Zmeys require F6 currently.
