Fair enough - I may have misinterpreted her post (seems that other posters took it the same way that I have), but I do feel it is more unusual than not for a solid international team to be put together last minute. The Lionheart team has been advertised since summer, so even they were not put together in the 11th hour. I took her post to mean that it was common for International teams to practice in a similar manner as this Lionheart team and such teams are competitive at Worlds, and I find it hard to believe that the top teams operate in any way similar to Lionheart.
I have no issues with whichever route a team chooses to take - if a bunch of athletes want to get together from all over and practice every once in a while and go to competitions, that great for them.
