My thought is to bring the same (or similar) lists and armies again, and try (try again) with a slightly more overt ranking of “Tasty” to “Crunchy” to “Just Plain Mean” to best calibrate to what my opponents are using or how they’re playing that day, which suggests to my mind the following hierarchy of sportliness and competitivosity:
Light & Tasty: SM Dreadnoughts
Crunchy Fun: Tyranid Warriors
Just Plain Mean: Slann (Tau)
I KEEL you: Sisters of Battle
More on this as things develop.
