Hearthstone legend . Is it credible?

Absolutely unbelievable. First, if there is such a big loophole, Netease and Blizzard can't fix it for several years. Second, Netease is very strict in investigating and dealing with illegal cheating. One or two days before the derailment, the slowest two months, you will definitely receive the title email. Take storm hero as an example. Most of the training on a treasure adopts the way of automatic scoring. It seems that it is not illegal to just brush heroic experience, but most of them will be regarded as titles in the future. So if Hearthstone has such a big loophole, Netease can't be unaware of it.
