What if retal rights weighed attacking KD KS?
For instance, if Im at 10k KS and attack someone at 7k and get a castle and drop them to 4k ks. Because I hit at 70%, I can be pre/re by any combination of kingdoms that make 130% of my KS. So if I hit 12k while the retal is active I can be hit by two kingdoms who's KS does not exceed 15.6K KS.
Attacking kingdom still gets CLI to precent passing, so the person with a retal can designate their chosen ally to pre for them so long as they are within the KS total.
That way you cant castle pass after bottom feeding, you only pass land, and the designated pretal and retal could break through either way.
