How to unlock the Dominating achievement in WWE All Stars - Definitive Guide
I found this trophy harder then other trophies as you can not use another controller for this trophy. Though if you pick the handicap mode and make it that your on the team with two people it will make the trophy easier as during this time, your opponent won't be able to attack a lot. I suggest you stay back and only attack if you know for sure you won't get hit. Also watch out when your opponent gets knocked to the ground, as when he comes back up he will kick anyone in front of him.
Check out this video, it's the best method for this Achievement and will also unlock "Layeth the Smacketh Down!" if done correctly.
