Although players often consider jungling to be a role exclusive to League of Legends’ Classic gametypes, proper exploitation of the jungle is vitally important to success in Dominion as well. At the lower levels of play, players often feed too much information to the enemy and allow their foes to move through jungle areas unmolested.
Never do this! When you’re ahead, the most important thing you can do in Dominion is secure your lead further by limiting the enemy’s movements. The only way to do this is to control the jungle. If you’re familiar with the idea of warding the enemy jungle to limit enemy movements on Summoner’s Rift, controlling the jungle on Dominion will likely be familiar to you.
