What's the ideal Dota team composition? You might be thinking that the answer is something like a carry, a semi-carry/initiator, a pusher, a support and a disabler, or something along those lines. That would make sense right?

A one-carry, two-disabler team (which represents a larger chunk of test data, 3%) with the other heroes filling out the other roles -- pushing, initiating and support in different combinations is probably best. This team should win 61.2% of its games, again assuming that all other factors are equal.

The very worst? Five carries and three initiators, which will win just 31.9% of its games. That's not an 8-hero team, by the way, almost all heroes are flagged with more than one role.

Skip Riki this time, take one for the team, and you'll be far more likely to bring home a victory.
