I've scarcely started SB content, so nowhere near this yet, but, how do you suppose they can kill premades for a public dungeon without nerfing it into the ground?

Sounds a bit like an unfortunate consequence of circumstances. How do you create the "public dungeon" type content, with the level of difficulty they intended, without having it fall victim to the premade mentality?

Perhaps also worth examining the JP popluation's views of the whole thing? Are they seeing similar reactions, or do they approach this style of content in such a way that it doesn't result in such animosity?
