As someone who covered Call of Duty World League, among other Pro Gaming events, I was genuinely impressed by how Blizzard rolled out OW league.
Obviously, we'll see how it completes the first season/playoffs/championship etc, but from a purely aesthetic standpoint, they nailed it.
The only thing I felt CODWL did better was drop the worst performing teams at the end of the season and allow in new teams who performed well in qualifying tournaments.
I do like the idea the of treating OW like a Pro Sports league with set teams and so on. Really curious to see how this progresses.
