POT 1 -> Bigger Clans (3, 4 or 5 clans with more players) [30-33]
POT 2 -> [21-29]
POT 3 ->[16-20]
POT 4 ->[11-15]

POT 1 clans go automatically to 1 group each. (in a 'seeding system' style)

Then POT 2 clans are drawed to a group each. The same for POTs 3 and 4.

No clans from the same POT can be in the same group. The group format will be the next:

Group 1 -> POT 1 Clan (Technically the best), POT 2 clan, POT 3 clan, POT 4 clan (Technically the weakest)

The number of groups and clans per group would be decided depending on how many clans join. Also POT divisions are an example.
