Arc Star Nerf
Not the damage nor the explosion radius, but simply how the grenade works. Being farther away from the center of the Arc Star should proportionally stun you for less and less, with the full stun time occurring at 1-5 meters in explosion radius, and scaling down from 6-10 meters.
Arc stars have a blast radius of approximately 10-9.6 meters. Within said 10 meters, being within the center 5 meter radius will cause it to do full damage to shields, and being past 5 meters will reduce said damage. Independent testing of marking a spot and moving 5-10 meters away from it reveal the arc star does approximately:
1-3 meters: 125 damage
4 meters: 112 damage
5 meters: 100 damage
6 meters: 75 damage
7 meters: 60 damage
8 meters: 25 damage
9 meters: 12 damage.
Yet all 10 meters will stun you for approximately the same amount, with the arc star stunning for just a hair longer at 1-4 meters, despite doing wildly varying amounts of damage.
