One of the main things that makes the fireteam so broken and OP is the 1011 pistol. If Illfonic just nerfs that pistol and nothing else, the balance of the game can improve by a lot.
The fact that you can just melt a predator with the pistol, a secondary weapon, is insane. You can just switch from the Sawz or hammerhead and deal a ton of damage. The pistol also does good damage at medium ranges too.
If the pistol’s damage gets nerfed, the fireteam will no longer be able to just switch from their primary weapon and do the same or more damage than their primary weapon. This will force players to actually depend on their primary weapon mostly. Therefore, if they miss their shots with the Sawz, they can’t just switch to the pistol and start shredding the pred into pieces.
