That’s the entire point of the forges... You’re forging weapons of your choice. And actually no, it does not give the gamemode replayability at all. You’re guaranteed the weapon you want, the only thing you’re grinding for is a good roll. This is one of the reasons Black Armory was so poorly received. I mean seriously, when was the last time you saw someone do a forge??? There’s literally no reason to do them after getting a good role on the weapons, or getting the two exotics with insanely high drop rates. And now you can do every frame weekly. It’s cool to have something like this in the game, buy it needs to be much improved to give incentive to do it more than a few times ever. If everything in the game was guaranteed, it would be so damn boring. RNG is needed to an extent.
