This is nothing new, the game has been full of cheaters for months. Forget a feature banning cheaters from world war, that's only a small part of the game. We need them banned from the game entirely, but it's not going to happen because Nexon loves cheaters.
If you are new to the game take some time and read through the forum. You will see the extent of the cheating problem, and the fact that it's been happening from the beginning. That's about a year now and Nexon has virtually done nothing about the cheaters, zip, nada.
The only thing It seems we can count on is that the problem keeps getting worse every week and that Nexon will continue to ignore it.
