Hero pools and banning heros

I don’t see the reason behind this new “Hero Ban” test. Honestly, it sounds stupid, and limits which people can play who. I for one like that Overwatch gives us the rare chance to play any hero free and we’re not having to buy any heros. I cannot believe that you would let people tell you “to ban heros” because they “hate those heros,” it’s just them complaining over losing to certain people. It’s not the hero’s that are overpowered, it’s the people who play them, and you’re literally restricting people of their hero that they’re really good at, all because people are butthurt. Maybe think about that next time you “ban heros.”
