the Veterency bonus of M2HB is not working well.
V1 : Supperession +10%
V2 : Dmg +25%, Pen +0.5, Placing time reduces to 0.75sec, Barrel Rotation speed +40%
V3 : Accuracy +20%, Burst time +20%, Reload time -40%.
but the V2 is not working clearly.
I tested with both M2HB V0 and V3. but both are setting with 2.375 seconds.
Relic. see this topic, and fix bug right.
