seen some people say yes and some people no so
In general it works and I believe the Fireteam colors work as they’re supposed to as well (being for your actual Fireteam rather than three random players that replace your friends) along with the more frequent spawns of Scorpion and Wraith Tanks.
From what I’ve been able to get I believe there’s a couple problems with playing BTB in custom games and I think there might still be issues with particularly big Fireteams joining matches together - not completely sure.
All my problems are gone with it, and I had them the worst, so I would say yes.
