Hello there,
i just tested if Attack Speed is needed for Hunting!
left side is 5 Attack Speed
right side is 5 Critical Hit
i recommend the gear/consumables at 0:54
just hit the pause button :p
how did i test it?
i just started with 1 shot,
kneel down and empty current magazine with 1 shot
continued with 10 magazines (20 shots)
and shot once again,
stood up to shoot one last Time and watched at the final time
Critical Hits still deals about 200-250% damage and
Attack Speed gives about 10-20% shoot and reload speed
it is worth having both!
