Yeah, bandwidth and most of the back end networking is stuff I didn’t really touch on at all, mostly because I don’t have enough experience with projectiles with it. But I would assume that if BF4 can pull it off, so could others 
Jamendxman3 did have a very logical point though about choosing to do it the way he does (good backup in case things get messy performance wise down the line in development). But again it all depends on what you want. I personally am going to go with developing full on with replicated projectiles until I see a need to do it the way Jamend pointed out. Personal preference though
