User discretion is advised!
Picking a hero just because they are often picked in competitive matches will not magically grant you a higher win rate.
The same rule applies to heroes at the bottom of the list, for example, Zeus has not been picked at all in competitive matches, yet, he is the 6th hero with the highest Win % in Public Games!
So choose wisely.
Data from competitive matches that happened between 25/10/2012 and 18/11/2012 - http://dota-academy.com
Organized by the hero with the highest pick and bans to the lowest.
Centaur Warrunner, Drow Ranger, Silencer and Slark are NOT available on the Captains Mode at the moment, so I organized them by public games win %.
Zeus, Warlock, Skeleton King, Ursa, Spectre, Gyrocopter, Bloodseeker, Huskar and Morphling have NOT being played at all in competitive matches in the selected time-frame, they have been organized based on their public games win %.
