You hope you don't mean taking out barb camps with scouts. Barb camps are never a problem since you should be pumping out archers and upgrading them to CB for rush if you intend to go that way. Even if you don't intend on early rush, should do archers to protect settlers. Melee units don't even enter the equation except for capturing cities and meatshields. I usually only use the starting warrior to steal workers from AI. If you really want to do easy DomV, try one of the strong civ with broken UU such as Huns, Mongolia, Arabia, Zulu, China, England etc. You'll literally be playing a different game. Trust me Japan UA isn't as good as you think.
