I don't know if other people feel the same way, but the standard 'divison league' format just seems bland, uninspired and doesn't give a real sense of competition - it's not that the format is bad, it's just a psychological barrier that makes it seem more half-ass bland casual tournament. WNL has always been one of the best competitive tournaments, but that's mainly because of the reputation it's built overtime, even though the format is kinda meh. Having a division league format outside the WNL just seems off. ECS2 was extremely successful and for some reason the format felt good (even though it has flaws), adopting an ECS style format which caters to lower teams seems like a good idea and would be preferred. The WRL (although a really good tournament) isn't really 'exciting', even with some of these oldie teams coming back, need something to spice it up.
I quite liked the idea of having invited teams with other teams having the chance of entering the tournament through qualifiers, but obviously this wouldn't be implemented as there's not enough 'good' teams and the lower teams wouldn't really be able to participate unless you find an intuitive way of doing it.
