This is a suggestion which I think will rightly annoy a few people but it is incredibly necessary for the devs to be aware of it.
When you make a BR 2 weapon BR 3 etc… move it to after the BR 2 weapons, please. It makes no sense for players to research BR 3 weapons before finishing out their BR2 unlocks. It also makes it incredibly annoying to grind out equipment for a lineup. At least make it so that there is a temporary window where people can still research it with and indicator that it will be moved eventually.
I am convinced that this is what happens when high br claims to see low br, low br players simply have no idea about this whole system, they just equip the weapons they like and then for some reason find themselves against maxed opponents. This is unacceptable in my opinion, I know from experience that people generally don’t pay much attention to anything and in the long run it can be very harmful to the game. Matchmaking should select players automatically, if a player has to do something manually on his own, it is very prone to mistakes.
