Nobody sets out to only get a single kill with ANY super. From the Titan's point of view, FoH is a good solution if want to take out a group of players camped around the heavy/a control point. Let's assume then, for example, that there are 4 players in such a location. You now have to get within spitting distance of 4 players in order to kill all of them with your super. They are probably all shooting at you. It's not easy to get that close, is it? Now let's look at a similar super: Nova Bomb. I main a Warlock, so I'm very familiar with the pros and cons. On the plus side, you can achieve the same result as FoH without having to get too close. On the other hand, you tend to be firing it from waaaay up in the air - you're a massive target, basically. Plus there's a slim chance that they'll have time to move out of the way due to the animation/travel time. ALL supers can be countered. If you don't want to keep getting killed by FoH, don't let Strikers get in your face! Kill them at range - a scout rifle would work a treat.
