If by your logic hitting lvl 10 for 3 or 4 useless scrolls beats hitting average lvl 13 for a clean slate, I am sorry to say but your logic doesn't apply to my logic.
Poor design certainly justify the action because it is under no violation of glitch/ error in design (objective) under the ToS

so unless you want to bring the point that nexon can do whatever they want. Your point doesn't make sense

Nexon can do whatever it wants.
