This new division creates interesting situations.   A smaller gym may not have a level 5 team, but they may have more than several athletes (even half a team) who have doubles.  So their open 5 team could consist of half a team capable of doubles, the other half may have fulls, or are level 3 or level 4 athletes wanting to try a level 5 team.  And in the eyes of most, this would be fine.    Now, if the consensus is that crossovers between the two level 5 teams should not be allowed, and you have a gym who has both an open level 5 and level 5 because they want to give their lower level athletes a chance at the open 5, their strongest athletes will be on the level 5 team, leaving the open 5 to consist of athletes working towards level 5, and level 3's and 4's.   In this situation, which open level 5 team is at the disadvantage?  The one who has lost their strongest athletes to the worlds team of course.   Just another way to look at it.   I would hope gyms find a combination that is fair to the athletes involved and one that is fair to the cheer community as well.
