You need to decide what determines seriousness: the organization, as in your previous post, or the "straightforwardness" of the version.

There are resources that play on Equilibris, and there are those that play on Vortices. You want to move this resource to Equilibris. But there are few players on Equilibris, and it's unlikely that many will move here from the League. However, players from Vortices could realistically leave here. You can run tournaments on both, but moving all official tournaments to Equilibris, especially the World Cup, is not a good idea. That's my opinion.
