Normally jumping up and back wards or blinking can counter it. But you must be at the apex of your jump. Also, if the super were less strong than it already is, it would be total garbage. It's a one-and-done kind of super with pretty much no range (unless you have shockwave, which is very easy to dodge). It normally only grabs one, maybe two kills. It's pretty easy to spot a fiat of havoc before it even comes though, normally, any Titan sprinting at you is using his super. (Given he has enough time in the game for the Titan to have recharged it). The only other times I see this super used is what most call the "fist of panic" yes, this happens a lot, but it is a very poor use of the super, only getting one kill, most of the time.
