HotS Picker Assistant

So you have mastered Quick Match and now ready to get into Heroes League, but you have no idea how to pick a hero. That was my first thought when I started. At first I was like: "Guys, what should I pick? I appreciate your advice!", but it is not the best option.
What you really should do is to analyze, which hero is currently strong and suitable for Heroes League, how familiar and experienced I am with that hero, what is the map, what heroes do we already have, what enemy heroes can counter my pick.
I've gathered all this information from several trusted databases and created a formula that calculates everything for you in a real-time, which makes the Draft process really easy.

Please feel free to share your thoughts and I will try to make it even more accurate.
