It's a great idea overall, but requires a high level of squad cooperation - in an activity that you cannot queue up for specifically.
Eidolon encounters have an associated bounty for queuing purposes (in addition to being doable without the bounty)
Exploiter Orb encounters have an associated bounty for queuing purposes
Ghoul encounters have an associated bounty (it seems like it is DE's intent for thermia fractures to be the Orb Vallis counterpart to ghoul invasions?)
So why is there absolutely no way to queue up for matchmaking to do thermia fractures? Every time I've tried to do fracture runs since the first event, I've given up after 4-5 attempts because either:
1) No one else in the squad is doing thermia
2) I got dumped into a squad that just finished doing 4 fractures and is now disbanding. There seems to be some trigger in the matchmaking code such that if you load into a squad, and then the rest of the squad leaves, you will not have anyone matchmake into your session after the host migration.
