Yes this is in deed unfortunate.

However look at it this way.

During KvK.R there are 4 possible outcomes  for  your own kingdom, and your next  CvC opponents Kingdom 

#1 You  both win KvK.R....   No disadvantage to either side. 

#2 You both loose.                 No disadvantage .

#3 You loose KvK , they win.  Advantage to you.

#4 You win they loose.           Advantage to them.

So from a mathematical point of view , its only bad 25% of the time. 

ADDENDUM:

On a similar footing with regards restricting the access to level 7 tiles as suggested by the poster.

I would like to see L7 tiles restricted, in the same way as Gold of the Gods tiles are, as was stated  in the text ( but is it out of date?) 

I  would also like to see the same kind of distribution of Level 7 tiles as you get with Gold of the Gods, to give lower level players  throughout the Kingdom  a  chance of  getting an equitable share of the win. 

After the competition  closes, there would have to be some kind of device in operation to stop the strong players porting around, away from the spot they were in, or return to,or its general locale, in order to  take advantage of a kingdom wide distribution of L7 tiles 

Though it could be one of many reasons players are quitting.

As I have written elsewhere, there is no compulsion to take part in the competitions.

Problem solved.????
