Your biggest problem with LA Ermor in MP will be that absolutely everyone will be out to kill you the second they encounter you since your dominion will kill their population. That frequently means that anyone and everyone on your borders will gang up on you just to get rid of you and divide up the spoils before they are ruined. There is really no good way for you to use diplomacy to full effect because of that handicap and your hordes of chaff are there basically just to absorb hits before your real troops (most of them summoned) get targeted.
