As far as armor goes?
No,they cant.They will give out Req points once you unlocked everything.
No. There would already have been a riot if that was the case.
They’re not supposed to. I’ve seen one report of a player getting repeats, but did not see any evidence from that player that they were actually getting repeats.
i never received any duplicate permanents and I have completed my REQ collection.
The Halo 5 req system should not give out any duplicates when it comes to permanent req items like Cosmetic items, Warzone Loadout items and Weapon Certificates. If there is nothing left in the pool, the game will either award you an none permanent unlock like req points or a warzone/arena boost.
If something seems like a duplicate, chances are it’s a recolor or they added an extra stripe. In this game, there are armor variants.
No, which is good. It happens a lot in Battlefront 2 and I find it pretty annoying.
What is probably happening is players are getting the varients and not realizing it. For example I use technician armor. It’s variant is technician “override”, which looks exactly like it except a few different color pieces essentially. It’s really hard to tell the difference visually.
