If you've thrown a grenade or semtex in Advanced Warfare, you know you have pretty good range. You can launch grenades across the map.
In Black Ops 3, it feels like your character is short arming his or her grenade throws. It feels off and you simply don't have the kind of range that you get in Advanced Warfare.
This was something that we saw many beta testers complain about and our hope is that Treyarch finds a better balance because grenades (both lethal and otherwise) play an important role in Call of Duty.
If it doesn't, you'll have to figure out a way to manually improve your grenade throwing in Black Ops 3. See the tips in the video above.
