I'm sure allot of you have heard about the A-Z challenge. It is a quite simple and brilliant way to learn every hero by starting of with playing the first hero on A until you win with that hero, then move on to next in the list until you hit the last one in the alphabet. This would be cool as a Match Making setting, like the limited hero option. When you have won with the first hero on A, and still have "this" matchmaking option on, the hero is no longer available to pick. I usually recommend my new friends to do this, as i personally think its a great way to learn what every hero does and how to play them. But I can see how some would think it's a pain to play heroes they are not comfortable with and when it comes to new players playing heroes like chen and meepo, oh boy. But still, its the best way to learn imo. Making it a matchmaking option / as a challenge, I think it could motivate ppl to try new heroes and improve their picking pool. And there is something rly rewarding about finishing a challenge. But to motivate ppl more, make everyone who plays this mode get 25% bonus bp or whatever. Thoughts?
