Lol, ok, well thats an easy fix, just introduce war like restrictions on outside kds. Like make it so that no other KDs can interfere with the 2 warring. The 2 warring KDs enter war stance immediately on commencement of the countdown. Theres 0 gains and 100% op failure from all exterior KDs. Also only intel ops can be done between the warring kds. Honestly though, your counterpoint would be a minor issue, that would probably only happen in the upper tiers. Fewer alliances down in the dogfight.
