I'm glad RU was included, and agree with ENZ0.
While LC has a smaller playerbase and number of battles, making it harder to justify including, its playerbase is established, they have shown good activity in tournaments recently, and the metagame has been developed for awhile relative to most other BW metagames. I would have liked to see them given a chance in an official tournament, but other than that, I'm pretty happy with this resolution. (Disclaimer: I know nothing about LC or RU as metagames.) I feel like including it in SPL would have boosted its activity. Hopefully the LC ladder will be more active next time and can be reconsidered for inclusion in SPL.
