Head-to-head history – while the eSports scene is quite dynamic and roster changes tend to occur far more often than in traditional sports, past history is another factor to consider before placing a bet. Try to find stats of the clashes between the two teams when the teams have had similar rosters, as well as the outcomes of games between the two sides in key recent tournaments.
This is also useful for single player games such as StarCraft, where some players experience great difficulties when facing a particular player because of his playing style. It is not uncommon to find one player with a dominant record over another despite the two players being quite evenly matched on paper.
