The information provided doesn't really go into great detail as to what exactly will be done to Dynamis. It's interesting that only the non-Dreamland zones were listed, although not sure if this is just a case of forgetting the other zones when making the post.

First off, there's this requirement of entry of once per Earth Day. This makes me curious as to whether the same time extension method will be used when entering. That is, are you going to hunt down those same time extensions to max out your time? Will they just give us our max time when entering now with the changes? Will they set a brand new time limit or just remove it altogether?

Triggers for certain Notorious Monsters. This already exists in a way for the bosses as we have to kill certain NMs before we kill the zone boss. Will they extend this to certain other NMs as well? Off the top of my head, some qualifying NMs may be those that are required in Relic Progression such as the Beaucedine and Xarcabard NMs for Attestations and Fragments. However, even these already have some requirements whether it is to get them to appear or actually make them drop their item.

Monster distributions will receive drastic revisions and monsters will yield experience points. I'm actually sorta excited about this one because it'll feel somewhat new for at least the first week. It can be nice when you find yourself expecting something and then Hello! This might also allow for specific areas if multiple groups are within the Dynamis zone are hunting down their currency and relic. As far as experience points, I doubt this'll overshadow the current popularity of Dominion Ops, but it would be a nice bonus for those returning 75s which I see every so often.

Given all this information there is still a lack of knowing how all this will be implemented. We know there'll be the day restriction but still don't know how this'll affect us when we're already inside. New monster distribution could allow for some good places that might allow for group separation so that we don't have to interfere with each other (assuming in the first place that monsters will respawn and we're not being separated into FF-type instances). Monster triggers makes me speculate again that we might be sharing the same zone and triggers were what we had demanded for open spaces like sky oh so long ago. I will be wary like many are, but at the same time I always get excited when something old becomes something new.
