Is there any exploit that has been discovered that negatively impacts anyone's game?
Exploits are exploits, Im sure they don't really give a shit about whether or not it negatively impacts anyone elses game to be honest. Its going to be a blood bath too if WoW is any indication. With WoW they were clearly monitoring for a long ass time prior to the first ban wave. Weeks and weeks people botted and exploited, then a warning goes up and supposedly those people stopped.
Then D-Day hit and shitloads of bans went out on the current exploiters and the ones that used them in the past. Hilarious times on the forums for days after that. Hope we see that this time too.
