Console: Xbox One. Game link provided. There is little as frustrating as playing a weekly strike, getting the boss's health to less than an 8th of his health bar, and going to reload the Gjallarhorn after using a heavy synth in order to deal the killing blow, only to have my character booted to orbit, or worse, all the way to the title screen. To add insult to injury, my teammates then tell me a random has joined and before they can boot him from the party, he kills the boss and my loot along with it. Can we lock fireteams in matchmaking activities like the Weekly Strike (or the upcoming level 28 Prison of Elders content) to prevent this type of thing happening?
