ENY is the best example of punishing players for not doing something against their self interest in the game. It was imposed by Hitech without input from the community to save the community from itself. Since then any subsequent ideas the community has come up with entails punishing others for not making right minded choices, being in the wrong place at the wrong time, or being too good at playing the game.
No one has come up with any ideas, they have always put lacy drapes on some variation of "punishment" to force up to 2\3 of the arena population to act against their own self interests. Players pay $14.95 out of self interest, not for social justice. You can see how that is working with ENY.
Currently the game is populated with a majority of veteran players who are unwilling to put any more energy into the game than it takes to pick a few kills and feel good about themselves. They know just how much effort to expend to not get towered while looking for the moment to pick someone. And they are good enough at the game that the veterans chasing them can end up with a draw on their engagements, if no one is trolling around poised to pick. Punishing veterans will not change their knowledge of how good or bad they are at the game and how they play the game to compensate.
Every invitational group activity like the "Kill Kraby" or "Monday Night Madness" with their conduct rules ended up with the players compensating for their own self interest once they reached the limit of their abilities so they could win fights. In 15 years, all of the ideas to improve the game like you want to thrown out here, are frilly drapes to try and make appealing punishing players for none compliance, or just being in the wrong place at the wrong time while seeking to win any way they can for their $14.95.
Let Hitech decide how he wants to punish his paying customers for playing to win at a personal combat game. A good idea would be how to give them more ways to indulge personally winning for their $14.95. I've seen very few of those over the years.
