In general, yes, I would prefer to have the exact same sets as the Japanese sets, and I'd prefer it if they'd release our sets closer to the same time as Japan (translating really doesn't that THAT long. Just look at how fast fan translations show up).
HOWEVER, there is one huge exception, that being Lost World, and Lost Remover. I don't want those to be in the US sets. Why? Well, they are too good. Beyond just being good, they hurt our format far too much as well (Lost Remover would make Sabelock and Dialgachomp unplayable, and would make Luxchomp even more amazing). Some would prefer them to still be released but then banned, but I'd dislike that, as banning cards is just confusing to younger players. It's better to just not have them exist here than to ban them, for simplicities sake.
