Also, if you ever want to have a lot of fun with a couple buddies, play a support with CV, have 1 buddy jungle, and another dude wherever. Use your CV on the blue/golem camps and the wraith/red camps.
If you rarely jungle, or just aren't that experienced, you may not know what the information you're giving your jungler means, but he will. For example, I just played a ranked game as Udyr against a Tryndamere with Taric as an ally. Tryndamere has multiple jungling paths, so I was afraid to invade him early at wraiths, since he would have done them already if he started Golems first. But once Taric CV'd Wraith/Red and found it still there, I knew that Trynd had done Blue First (with help from Morgana), so I invaded him and stole them.
Over the rest of the match, I kept invading him, stole red twice, and eventually outleveled him by 2 levels.
It's really a lot like a spy mission, where one dude (the support) gathers intel, while you are the actual field operator.
