your abilities aside lich emperor from a mechanics POV can beat damn near anything solo, and that was before edges. You just conduct your fights in a way that are supremly uninteresting to fight against because everyone knows your just in it to seal kills. So you exploit all the tactics that make people just not want to deal with you. I mean your a friggin lich emperor try running around without zombies a little for a change. Or try not walking around in a gank just because you happen to have people to gang with (your previous emperors seemed to do that constantly) I mean look at igbah, the dude was a beast but everyone had nothing but respect for him. Not cause he would go suicide himself but because he fought with class.
