Hey love,
Recently geared this bad girl up.
If you are willing to slog through 4 m0 runs you get a heroic nathria item this week maybe you’ll get lucky! Furthermore the campaign does give a 187 (not 200 but it’s better than the 140 you get from story). Have a 220 offhand and that 187 main hand now 
Edit ANOTHER IDEA ;
Honor will carry across the reset and you can use that to buy a decent weapon off the bat in like two days. Farm honor hard and fill your empty slots.
