Because golden gun beats defender bubble, and fist of havoc beats blade dancers. Hunters ( the class with the most clearly OP pvp supers since launch) whined and complained about FoH so much (despite their supers being far more unfair) that Bungie made sure their new super trumped the new Titan Super. Incidentally, I had HoS active the other day and ran into a storm caller. I hit him dead on with a hammer, and before I could throw another his lightning killed me. In other words, the new "OP" Titan super loses to the other supers. Again.
