I am one of the many that do not agree with how Dynamis has been updated, I understand why they took the approach they did, unfortunately they were probably expecting people to flock to this event. The stagger system should have definitely been left out, the monsters do not last long enough, and with there being a severe lack of safe areas, you don't want them to, also the lack of time does not support this like abyssea does with its unlimited time extensions.
The way that would have worked better is to allow groups to enter like they do with Nyzul Isle, have the NM spawn as they did before, but instead of using the same number of monsters, set it up to be similar to Garrison, where the amount of available monsters is related to party/alliance size. This will make it both low-man and large group friendly, as mentioned earlier leave the stagger system out as that is a Abyssea mechanic whose only relation to dynamis is the avatar that is suppose to rule the realm. I do agree with having the currency drop rate lowered from before, but without the stagger system as suggested, make the drop rate for single currency say 7~10% depending on the monster, and for the 100 value currency, leave it as it was, and also add a bonus for achieving victory in the area for those that already had the title/KI to get to the final 2 areas. This bonus could be currency for example, getting 1 piece for every 5 monsters killed, with a bonus of 1 per named monster.
These items would bring the life that SE wants in dynamis, while making the relic weapons and gear upgrades more obtainable without the huge gil cost of the hourglass.
