I think the idea to make brown broxes more easy accessable for non-cashers is a bad idea. Brown boxes are one reason why pve is getting destroyed and now with the upgrade update where items won't be break anymore you would ruin the whole pve with that. Even now no one goes to farm items in pve only accessoirs or cc dungeon. On tw items could break and white stones were not easy accessable also it was hard to get alot of stones. So there were two options you had. Spend money and hope that your item won't break or farm. It was worth to go to papaya and just farm items. But in dbog farming on papaya is nearly useless. You will only farm for stones because there are so many brown boxes (brown boxes from cash shop are not even bind) that it's not worth farming items.
you do realize once people have to spend absurd amount, for example cashing for brown boxes just to keep up with other players they will literally just find a different game to play. The whole devalue PvE stick doesn't work for a community base private server which the grind is suppose to be less of the original game.
