Does anyone think the heresy would have turned out different if say key characters would have stayed with their traitor legions, like Loken, Torgaddon, Garro, Tarvitz, Iacton cruise? I understand they are only single warriors however say if Loken and Torgaddon would have stayed with their traitor legions sons of Horus the mournival would have stayed complete as opposed to Abbadon and Aximand in the warmasters ear.
