According to the often wrong Prima Stategy guide:

T21:

Zero: -90

Mid Range Mod: 0

Max Range Mod:-10

For reference: Laser Rifle

Zero: -80

MidRange Mod: 20

Max Range Mod: -50

Does anyone know exactly what time this T21 patch hit Eclipse (or other servers) ?
I was hunting early this morningabout 2:00 Central Standard Time (GMT -6) and didn't notice extraordinarily high numbers for the T21.

However, because of the slow speed for my T21 (9.1) I was mainly using my Laser Rifle.
