damn, thanks for clearing that up.
do you know why they've decided this approach and if they plan to implement matchmaking at any point?
i'll try inviting people again later but i think this is the end of destiny for me. it's a slow grind but it's been quite enjoyable (or i wouldn't have played this much) but this is just gonna slow it down even more.
Nightfalls are tests of skill and survivability.
Similar to Raids, you need to put your own team together to have a chance at success.
Nightfalls can be soloed, but it takes a whole lot more out of the player, and a level at least 29 is practically mandatory.
You are on gaf, check the first post in this thread, you will see a list of people you have an opportunity to play with.
If you are just a solo player, then destiny is really not for you.
Everything in destiny is co-op, and asks for team work.
