I believe the game would work well with projectile mechanics just like games implemented in pubg, fornite or battlefield series since APB maps are large scale rather than having an abstract concept such as hitscan.
It will make gunplay a lot harder in order to accommodate for a target's movements a player will typically have to lead their target (that is, aim ahead of the target's direction) in order to successfully make contact. In close quarters, the target will be close enough that velocity will not affect hit probability.
Pros:
New gun mechanic.
NHVR harder to use.
Bullets are server sided, the statistic of cheating can be easier to detect.
