To say nothing will be done, is wrong, lots of people spend time listening and reading ideas and issues, that's generally why forums have an 'issues and ideas' areas
In regards to team drop outs affecting the competitions, this should never really be a big issue, as;
9.A Dead Teams - Scoring
If a clan dies during the season the following procedure will be adopted:
If the clan has 3 and more unplayed matches, all scores from matches this clan took part in will be removed as if they had never been played. If the clan has one or two unplayed matches, the remaining opponent(s) will be awarded default victories.
So no teams should suffer massively, unless of course, there are numerous drop outs from that league.
I do agree, however, that it is never good to see a team drop out, of anything, especially a 'big' competition, like the nations cup. This is unfortunate, but as with any game, and/or sport, things like this always have, and always will happen, it can be caused by anything such as member inactivity, or a clan leader leaving to set up a squirrel farm. Checks are made at the start of the season to make sure all teams who sign up have enough players, and that's all that can be done for anything really, despite my personal best efforts in Black Magic, no-one can change someone's ability to complete a competition if they're not able to one way or another.
Hope that i've helped you a teenie tiny bit and that you feel someone has read your opinion, however meek and humble i may be
