Setting up bigger challenges can be a nightmare when it comes to getting all the team members available (for both Clans). Most players in our Clan 295
are not only willing to participate, they are really looking forward to such events, although some of them prefer to be not included in smaller challenges at the same time. I guess that is similar for most active Clans.
Would it be possible to have two levels of availability for Clan challenges? One that do not allow being included in any challenges (as it is right now), and a second where the player is still available for bigger challenges (e.g. 15+). This would make setting up bigger challenges a lot easier, and I am sure much more bigger challenges would be played.
