Well the problem is that the clan that leaves dosn't have to leave due to closure.. There have been some clans who just left due "camping" and other brilliant and 110% understandeble reasons..
If someone decide to make another season of the league I will support it. However, due to all those facts Haur mentioned its easier to run a tournament. Because, if one clan drops out it will only affect its opponent and not an entire division.
The AQ2W league is a great idea, though it should have a maximum break between the seasons like one month. The way it is now is quite useless and time-wasting. Every season is a league of its own.
That's why a tournament would be much better. Champions league style is good, also cup,... But maybe there should be a special kind of tournament adjusted to AQ2. Clans are clearly the biggest issue.. Maybe some qualifiers would fit well for the 'unstable' or new clans. Older ones are seeded etc.
Anyway, I don't think anyone will be up for making a new league season. Unless clans start cooperating with the league staff, but that won't happen in this millenium.
