Bounty's in the open worlds

[(XBOX)PsyCrowPrime]

Between the lack of amount of time to complete certian challanges, the lack of enemys spawning to complete a goal for the challange and the massive area's in with the radius of the challange's exists in being far to big to find to all the enemys, its hard to complete the bonus with not fault of the player. Eg. When it says to destroy say 100 enemys within 4mins remaining but being at 2mins 30 seconds left on the challange at 85 kills and nothing spawning, something really needs to be looked at on the open world bounty challanges when in lobbies aside from solo. Happens way to often that we cant get the bonus due to mission mechnaincs, spawn rate, challange area size.
