This combines with the fact that they reintroduced the "volatile applied by gyrfalcon doesn't grant anti-barrier" to neuter this exotic in anything with champions. By removing pre-existing volatile buffs, then applying its own, you guarantee the player is using the bad version instead of normal rounds. Also, having them active before you break invisibility allows you to immediately chain them on shot 1 from invis. This is particularly important for low RoF weapons.
