Currently picking up missions at 20k I'd say about 1 in 10 of them actually gets to the boss.
Mostly the team never gets past 50% and even this takes 3-4 hours solid play.
Are there any mission booth settings anybody knows about that makes the missions smaller?
Alternatively people must blitz team missions - can we get some tips from those people here.
I'd imagine a good strategy to be something like,
Get a team together capable of taking on the boss.
Keep the team at the entrance to the level and get a fixer or agent to find the next elevator.
Fight a straight line path to the elevator and repeat for the next floor till you reach the boss.
Or
Maybe get an engie up to outside the boss room and warp people up?
