Seeing as how this is a suggestion thread to the dynamis developers..
I suggest not making dynamis like walk of echoes. Each party should have their own loot pool.
I suggest making it an open zone.. with mobs distributed to where you don't get 50 at once
Everything would respawn super fast so people could farm without concern of overcrowding.
MPK shouldn't be a huge issues because mobs should be able to despawn.. like normal exp mobs
and I think attestation NM's / zone bosses should be force popped and limited to once a day...
I think an accountability system similar to fov elite regimes would work best.. to prevent a group from taking turns popping NM's with each member..
the current fov elite system is.. you have to be in the group when the NM is spawned.. and if you aren't.. you can't assist in the fight in any way.. even if you join the group after.. you can't heal people.. you can't engage the NM..
With a system like that.. you could make the group lose their key item when the NM is spawned... and keep accountability of who has fought the NM accurately.
