Specifically:
*Are there new story elements/cutscenes?
*If the above is true, how long roughly to complete it?
*If the above is not true, is the Incursion main element, essentially just another "mission/raid" that is played on Super Challenging difficulty (judging by what the devs said, who couldn't complete it)
*Are you just repeating Falcon Lost over and over, in the hopes of getting new gear?
*And same for the DZ, just kill players/supply drop enemies, for better gear?
So that after a few hours, you could, through RNG luck, have all the new gear, and then its business like normal, return to the DZ higher levels, kill them for HE gear, to become stronger, rinse and repeat?
It doesn't have a story, but if you pay attention there are details in it that hint at where the story will be going.
How long to complete it will vary greatly depending on the group.
Yes, the incursions main element is akin to a raid/strike that is normal for this sort of game.
Yes, the point of Falcon Lost is team play. You will be playing it over and over, and loot is the obvious reason to play it(other than fun).
This is a loot based game which is loosely based on an MMO. Not really sure what you expected. If all you want is story missions then you will have to wait till June.
