it's a little less useful at early levels because people are less in tune with aspects of the game like jungling, ganking, and dragon control. Clairvoyance is most generally useful for a) finding the enemy jungler (either just to know where he is or to prepare to counterjungle him), b)checking dragon/baron/bushes in which you don't have a ward at any time from anywhere (which is important when the other team has gained map control), c) avoiding ganks (this mostly comes with practice and also ties in with part (a); you can use CV to either keep tabs on the river next to your lane, or use it to check a bush before you walk into it, etc., and d)to give your team a chance to retaliate against those annoying people that snipe you with skillshots from the other side of a wall. Basically, it's a free 10-second, larger range global ward. It's not going to be as useful at lower levels, but learning to use it early can give your team a huge advantage. As for the reason you take it on sona or soraka, it's mainly just because they don't particularly need any other summoner spells, and they're better off taking something that benefits the whole team.
