been reading a few of the other threads, and a thought occured that hasnt really been looked at from 1.0 and something that might make for a good 4th dungeon going forward, and thats that 1.0 had non instanced 'dungeons' like nanawa mines that could utilise the better aspects of eureka and diadem to make for an overworld area where people could grind for things while fixing the instanced issues of lack of party finder and the ability to grind things inside while waiting on queues (downside is also means this area cant use crossworld functionality without some huge overhaul of duty finder)

the other thing is while i know everyone hates totorak as it is now, the underlying ideas in a multiple choice dungeon crawl from 1.0 (yes i know 1.0 only had 4 dungeons) could work again going into 5.0 with the new areas, a sort of twist on old ideas, and having one of these longer dungeons on the off patches similar to the HM dungeons on the even ones could be a nice change of pace without straying too far from what does work in the game (of course then youll likely run into the potd/hoh/old msq problem where assholes only ever want to speedrun and must go faster and ignore all the exploration and chests gimping anyone who actively wants to do the content)

but those are my ramblings and i think the failures the devs have had in diadem and eureka and the dd system may make the things people liked about them resurface in interesting ways in 5.0
