I play voidlock in crucible and always try to save my bombs for heavy ammo so I can take the whole team, other times I will use it include: Titan bubble I hate those things, blade dancer I hate them things too, if I see whole team on a point then it's getting used. Most of the time it is pretty pointless using your super on a single target. But I do feel that there are times when hitting a single target was the best thing you could do for instance trading your super to stop a blade dancer tearing through your team and as I said before destroying a Titan bubble so he can't control a point. I don't think it's the most efficient use of your super to hit one target but sometimes it's a fairly effective use of it, especially if you are trading for opposition super. It sounds to me like you think kills is the be all and end all, but using supers tactically against single targets may not reap instant rewards but your team may still benefit in the long run.
