While I would have liked to see more diversity hit Top 16, I'm very pleased with the way the game is developing. The new wave this week is going to introduce some additional diversity to a trait that was sorely lacking, and the wave after looks like it's going to make a big splash for Force Users and perhaps brawlers.
I think what we saw at worlds was, as it was last year, a disproportionately large number of players bringing a safe and consistent list. While the Rebel and Imperial figures introduced in Jabba's Realm require different lines of play than we are used to in order to work, the Merc units (particularly the Weequays) played a much more straightforward game of building up focus for an explosive round 2. The few matches I watched on stream it seemed like everyone was playing extremely cautiously and not pushing their opponents very hard when they got an advantage. I don't know if the swiss rounds played out similarly, but that was my observation.
