Not Enough Leaders

[Poor Yorek]

Could be typo or possibly the designer was thinking (or was told) that there would be seven LTs in the mix and so wrote the scenario that way and the problem wasn't caught after the final decision for leader counter mix was made.

If there are scenarios related to this one and you don't mind spending a bit of time data mining, perhaps you might try calculating the leader/unit ratio in those (or similarly sized scenarios - presumably a relatively large one to use up the LT pool) and then test against using six or seven in the one proposed.

There is also the old fallback position: use a binary decision generator.
