Ended up as Red*army|Amaranth ( or similar )
he moves like a real pro, and seems almost psychic about where people are or are going to be.
i watched for a good while; it feels like he is cheating but i cant say for sure: if not, then he is very, very good at this game ( and i have met a few ... )
i took no action in-game - does he have a WH ? ( but i'm pretty sure he's not using an AB )
