Summoners War Hot Issue - 100% Arena Win Rate Bug

There has been some grave issues regarding the game security of Summoners War. Apart from the hacking issues, the glitch/bug for 100% Arena win rate is another hot topic.
The initial video I can find regarding this was posted by Youtuber AlanGaming as embedded below. He provided clearly how the bug was done and added how he felt regarding it. Obviously, nobody is going to be quite happy with it being exploited.

Further, a more prominent name in the SW community - Claytano, made another video of trying out the bug for himself. As seen in his video, the bug worked as well leaving Claytano somewhat at a loss for words. Quite understandable since the presence of such a bug brings attention to one of the currently monumental issues of Summoners War as a game.

Personally, I am also quite bothered with the presence of such bugs. For a game that has been in the market for more four years now, these bugs should have already been dealt with and be fixed at the beta testing phase. My reaction to this could be summed up by the rage comic below.
