I would wager that the sight was initially added because people were wasting the first shot trying to find the target (since it lights up the area as the beam strikes). I personally don't see this as an issue, per se - I often use Kog'Maw's ultimate to scout brushes and such. However, for the cooldown and the number of strikes, wasting one of them as a CV probably has a negative impact on the skill.

They could go with shortening the duration of the sight, and make it feel more like a pulse (so it's a band of sight that expands, rather than an area).
