For the lazy:
Right now here are the stats:
Number of missiles: 18
Shots per second: 11
Explosion Damage: 8 (has damage falloff)
Impact Damage: 4
Radius: 1.5m (for comparison, Pharah's rockets are 2.5m radius)
Cooldown: 8sObviously these are subject to change, and I am sure you guys will get a better feel for them when we get the PTR up.
Reddit did the math and it is supposedly 216 damage potential over 1.6 seconds
