Yeah it was:
 * Legendary mono earth + mono air = cloud king or tectonic
 * Legendary mono earth + cloud king = guaranteed tectonic
 * Legendary mono spirit + mono fire = ruby platemail or blazeborne
 * Legendary mono spirit + ruby platemail = guaranteed blazeborne

So I'm guessing these combos that guarantee an epic as a result of fusion weren't something that Gree was planning on. I doubt fusion was intended to be such a sure thing. I hope they will figure something out and put the epics back in the fusion table, although I'm sure the rate will be much lower.
