This build works just as well during a Dominion match as in a 5v5 match or a 3v3 match. The difference being that instead of getting regens, you might wish to invest in a lifesteal item earlier than before. This being due to the fast paced nature of the game, you do not really have the time to sit back and wait for your health to come back. However, you may run out of mana if you do go for lifesteal so it is totally a matter of personal opinion. If you do go lifesteal i suggest stark's fervor. Some items within this build aren't even available for Dominion!! Starter item should be the brutalizer. THEN you can go for boots, and/or regens from there. Trust me, the added penetration makes you do near pure damage right off the bat. I would also suggest getting a zeal early game, and then later turning it into a phantom dancer. In Dominion you can never have too much movement speed!
