I envision it working somewhat like abyssea in a sense, where it can support multiple groups of 3-6.
Xarcabard and Beaucedine are easier to predict, since they have the room to support large camps of demons/gigas/orcs/etc... If a group wants to fight Prince Seere for Cleric's Mitts, they farm a pop item, spawn and kill it - and it'll be free for another attempt or the next group after a few minutes.
Shadow Lord perhaps will be spawned by collecting a Key Item from each of the major NMs.
It's tough to predict what they'll do with the city zones... and I can't see them having stuff like the Death House in Windurst anymore - as any idiot can gank the zone at any time in that case.
From the sounds of it - Dynamis will be "always open" like Abyssea - without the zone needing to "reset" like WoE... For example, if we're given 100 minutes in the new dynamis - we get that full 100 minutes despite anyone who entered the zone prior to us.
Also - it may be possible Kindred Crests and High Kindred Crests will be used as pop items for NMs in these zones.
Questions for the Devs:
- Many people are "done" with Dynamis. Will new gear be obtained from Dynamis along with these changes?
- Will there be an increase in enemy difficulty?
