Generally...
...players who finish 1st or 2nd in their league will advance and compete in the next highest league in the next Championship Tournament.
...players who finish 3rd, 4th, or 5th compete at the same level in the next Championship Tournament.
...players who come in 6th place or lower, will compete in next lowest league in the next Championship Tournament.
Also, league 2-2 is on par with league 2-1, so you are relegated by one level in this case
