back in the days people needed skill to play 19s, because it was a different game than endgame. Today, i'm afraid, 19s is like people always said back in the days, just like endgame with fewer abilities (which wasn't true in the past but is now). That's what i believe destroyed the community and the fun of the bracket, because it became less challenging.
It's like dota, it was a subgame within warcraft 3 to begin with, but unfortunatly, there won't be a company to take the concept and make a independant game out of it like valve did with dota. So i guess it's lost forever.
