Ok, you have another 75 test a kit to back up your point that the kits are not played/liked as much as the other. But that doesn't bring anything new. Eli made an amazing suggestion of a blacklist for kits, which would solve your problem, since you don't want to play hem. And all the players who, as seen in your tests, also don't want to. But It will still keep it for the players who do, seems like perfect solution, no?,
And I just did 10 games of hunter and no one left, only one person said, only sword. So let's say 1/10 "left". With this I don't want to say that you falsified your numbers but that even with the data you have presented now, it's far from enough to take one sided conclusions. Cubecraft has had (with bedrock since I can't find the numbers for Java alone) 145 000 players unique players today. You really can't take a statistical conclusion with only 135 games played.
