That and your team mates. If 920's are anything to go by, people ignore enemies constantly so you get less points, they don't have anti-champion rounds and they're not always very high power.
If this is about getting 100k, its been possible to hit 100k every week so far including this week on Hero difficulty. So, some of the people who want matchmaking for 950 strikes sound like they don't care about the necessary coordination for the strikes and think that everything should have matchmaking.
I'm not sure how hard it is to find a group on lfg or whatever but I'm sure it can't be that difficult, your odds of success would be higher there than if 950's had matchmaking anyway since ya know, communication...
