So I'm fairly new to game been playing now for about three weeks. I'm currently a 305 Titan and was going to try out the old raids Crota and vog but I've heard there pointless and to stay on King fall because there rewards are unable to be infused and they are way weaker then anything you may get as reward from King fall. Just curious as to if that's the case if I get a good gun in one of the other raids can I upgrade it as far as increasing my light etc. thanks.
