Get this, they found out a solution to block out the infinite amount of Obsidian and Garnets you could have gotten from Soul Boost by just putting a 14 Chars limit to. Also get this, they had to develop a system, supervise it, run through tests, approve it and lastly run it into life servers in just TEN DAYS! Because this issue was first ever mentioned TEN DAYS AGO! And they already created and developed a solution for something that will NEVER hurt their income.
But fixing M'Ao and Eva is way to much to ask for. I mean forget about Eva, you can still do duo runs. But just remove M'Ao from the Ranking System!! Why is this so hard?
