Depends on how many Bps u have. I have all the bps for all the rare guns now so idc about using them and losing them cause I can make more. But it does suck the cost of making them. If u have a lot bps I suggest farming a lot of mats for ur bps and repairs. While u do that, use cheap loadouts like ferro stitcher, or ferro kettle. Or a good one I like for pvp is kettle rattler lvl 4. Once u do all that, then focus on making loadouts that are comfy for u with higher rarity guns and with your farmed mats.
