So, there are "regular roulettes" up to expert dungeons, but how would you rank the other content in the game in terms of what would be the next step up? Like the next step up from expert roulette, then the next one above that step, etc.
Is there a general consensus on the increasing level of difficulty as a player progresses in skill? I know what the content is, just not how it stacks up if you see what I mean. Are there any big jumps along that path?
