How does education solve the issue? If people are bronze/silver, that’s the level they are at. They will always struggle when playing against certain heroes. This is natural in a game like this. Just look at LoL. It’s the same thing. Master Yi feels so broken in lower elos, but he’s pretty much thrash when it comes to high level play.
This is a skill gap problem, all the tutorials in the world won’t be able to solve it.
