if your weapons are already at 1000 or above, then no. but if you still need 1000 weapons, keep dumping them. those packages can get up to 1000 light.
*warning: incoming long rant*
been grinding IB and good thing I keep reminding myself I'm only doing this for the gear and I don't care about the outcome, because boy oh boy sometimes it just makes you want to tear your hair out... shotguns apes everywhere? Titan keeps shoulder charging and not using guns in a FPS? fine. my aim isn't that good either and if I have less self respect I probably would use them too. team mates keeps running into you and moving you while you're aiming? or blocking your shoot by moving in front of you while you're aiming? fine. I understand that people are just not aware of it sometimes. Hardlight everywhere? fine. it's a good weapon. (thou I can really do without the flinch they cause since having no dmg fall off AND flinch seems way too OP) but the one thing that bugs me to no end is the fact that most of the people I ran into on my team have no awareness of any kind at all. our team has A and the other team just took both B and C? guess what? they're coming to take A. just defend and shoot them instead of rushing out and getting yourself kill! we're down in scores and only got 1 zone? do some capturing! your teammate is shooting at the door way and have it covered? check radar and cover the side? Heavy about to spawn? go cover that spot! and check radar often instead of always ADSing! and for crying out loud, the IB is light level based so if you're under 990 light, why are you even joining!? sigh... at least I'm almost done with the bounties.
edit:
yeah, DFA while kinda cool in PvP, there are plenty of better guns out there. unless you're into collecting stuff, just junk it.
and yes, fully upgraded armor helps a lot, especially in terms of the mods you can put in and all that. weapons too. being able to get orbs of light whenever you get a double kill or more is really useful. thou you'll want to do some research on what stat and build you want before just blinding maxing any armor thou.
