That's very interesting. The PBall he describes as small, you get 1 peon, 1 paladin, one wizard(mage), and you use ice storm(blizzard). The pball he's describing sounds the most like 420 PBall which was one of the first pballs after 60 Man and was played when PBall was invented around 2002. You actually get 2 knights, 2 mages, and no peon in that map but he might be remembering wrong or its a different version of it. If he's not talking about 420 PBall he might be talking about some PBall build or an obscure PBall lost to time.
As far as knowing who he might be back in 2002-2004 PBalls heyday there were 100s of PBallers, but most of us knew of each other, especially the top players. I'm not sure what his aka would be but if we knew his aka there's a good chance I've played with him back in the day, or would remember the name.
Cool that Warcraft 2 was talked about on such a popular show, and interesting and crazy he was was a PBaller and brought up PBall haha
