Except sieged reload was never buffed.
Reload buff applied to non-sieged weapon specifically.
It was 10-12 for both modes, then non-sieged was buffed to 9
Sieged remained the same, then buff modifier went from 0.5 to 0.75
Yes because the intent purpose of the change was to buff the tank MOD and Siege MOD was buffed accidentally, since as I have explained both modes use the same reload. The only difference between the to modes are the ranges (at least in live).
Then they simply changed the modifier to compensate and bring the reload close to its original value.
Can you pls accept that you have made a mistake and simply move on?
