You don't realize how much damage you take from mobs in there or how much hp they have at stage 51-61.
What you're saying right now is coming from baseless assumptions because the dungeons gives a ton of xp. You realize there's a ton of variables within the aerodrome that'll make it next to impossible to bot it right? You've cracked down on Eva botters, why is there radio silence now, even though this is a much more considerable any other NC staff member? This can't ever be caught up on by normal players. It's no secret why/how people stormed hm40 (or are in the process of doing so) past month.
