SMGs are currently seen as the dominant weapon class in multiplayer and Vonderhaar has admitted that SMG penetration (where bullets pass through walls and cover) is ‘probably too high‘. Vonderhaar says it’s ‘something we’re looking at for the next update’.
Another confirmed change for the next update is that the score requirement to activate UAVs will increase. UAVs are currently the scorestreak with the lowest requirement to unlock.
There’s still no word on when the update will come through.
