You should look at the top suggestions and decide for yourself which hero you think works better.
You should pick the role that your team needs and think about the lane that you will go to.
The picker can help you go outside of your comfort zone picking heroes you wouldn't normally consider, but advanced knowledge about the picked hero is definitely recommended.
Even if you are using a picker it doesn't mean that you should pick last (you may want to leave that for your mid or carry so that they don't get countered).
Try to analyze why certain heroes work better in certain lineups, even if you do this after the game has ended. It will make you a better player.
Drafting and picking is a huge part of Dota 2. This tool will help you when making decisions, but you should use your own judgement.
The suggestions are calculated statistically from millions of games.
There are two modes used for suggestions, each with their own benefits. You can:
• Use advantages instead of winrates. This will favour a broader drafting pool of heroes and not only the most op heroes in the current meta. It is very good for learning / playing varied heroes in the best conditions they can possibly be played. (Advantage Scores Mode)
• Use winrates instead of advantages. This will favour the most op heroes in the current meta and give an increased chance of winning. (Winrate Scores Mode)
Charts and Bonus Points which vary throughout the game can be shown and used with the suggestions.
Selectors can be used to only show suggestions for specific lanes or roles. Matchup tables help with win predictions.
We have a premium service as low as 1$ / month. Besides many other things it adds bonus scores when calculating hero suggestions based on how well you played lately with each of the heroes. This should make the picker mould around your play style.
We usually update our data every week. It takes a while when a new patch comes as a day or two of gameplay do not produce a large enough sample to make accurate suggestions.
The data is taken directly from Valve, which provides the Steam Web API.
You need to expose your match data to third parties so that we can fetch it.
How to enable "Public Match Data":
• Open the Dota 2 game client and click the Settings icon.
• Navigate to "Options".
• Check the box of "Expose Public Match Data".
We don't have an iPhone or Android app, we think the best way to use a picker is inside the Steam Overlay Web Browser.
We don't. You're entering the user and password on Valves website. We are using Steam OpenID - this allows our application to authenticate a user's SteamID without requiring them to enter their Steam username or password on our site. We never know your password. It's safe and officially supported.
