Your call on whether to drop. My goal for the tournament was to make it so that the games that were played were “guaranteed” (to the level possible based on the data that I have/matchups knowledge that we know) to be even, and thus put more of the onus of play onto player knowledge of matchups, rather than player knowledge of unbalanced CPs. So, I wasn’t trying to force people to not play the top tier (@mysticjuicer has that covered with 19XX), but rather to make it so that it was safe to choose not top-tier because you aren’t going to get hard CPed every time. So, I can pick BBB (or Pers, or Ven) and know that I’m going to lose because I’m a terrible player, not because I’m getting thwacked with awful matchups.
Likewise, @CKR can pick always Zane if he loses, and as the winner (and thus presumed to be the better player), you’d need to respond to that by picking one of the balanced matches that you’re comfortable in/feel good playing. If you win, sure, he can pick Zane again, and you can pick your same balanced CP. If you lose, then you can force him out of Zane by picking one of the many characters for whom Zane isn’t in their options list.
