The thing is he gets the clones that are not up to the fighting standard set for the normal forces. Less then half a percent have some error in their DNA that weakens them down to around human levels rather then half human half dragon. That still comes out to be a large amount given how many clones there are, so he requested command over them to form his own personal army. He could still have a God complex, but he doesn't seek out perfect minions as is clearly evident by this.
