This seems like a pretty serious exploit and given how WQ works, I can kind of see how the exploit was even possible to begin with (there was a similar, unfavorable issue a while ago where WQ didn't start properly or didn't complete properly too). I doubt Blizzard appreciates players abusing this to absolutely destroy the pace of progression they set (which is important even in evergreen/pseudo-evergreen content).That said, I doubt Blizzard is going to issue much in the way of permabans. Maybe some long bans for players who seriously abused the exploit to fall in line with the progression rate they set.
The right thing to do when finding an exploit or bug, especially in an online game, is to inform the developers of it through private channels (which Blizzard gives the players in a very easy to access avenue), and hope they fix it in a timely manner. Not to spread the existence of the exploit and propagate its usage even further.Bottom line is: if you cheat at a game, AND GET CAUGHT, you deserve to be punished. Ergo, if you're going to cheat, don't get caught! Simple as that. Don't forget that you agreed to the EULA, which clearly states that Blizzard disallows exploiting and reserves the right to terminate your account at any time, for any reason. It's not your game, nor is it really your account. You merely agree to follow the rules and not be a complete moron on Blizzard's servers in exchange for being allowed in in the first place.Now we can only hope that Blizzard will follow up on this promise to "take action" and catch the people who obviously exploited.
There is a moral difference between completing a World Quest, realizing it's still there, doing it one more time, feeling weird & walking away after a bug report, and spamming it for exalted rep, 10s of thousands of gold and DE-mats.
Then those that are banned / lose their rewards will do a DDOS attack on blizzard for retaliation this like little children crying over a toy they took from the store taken away.
People saying they did not know it was an exploit need to think again. I won't explain the exploit, but let's just say you don't accidentally create and disband raid groups 100 times in a minute. Those who abused it deserve some kind of account penalty.
