Do what everyone else has done. Load up a regular strike until you get the corrupted strike. If you don't get it, then leave and restart. Then, bail and go to the blind well and get your kills there. Also, use Fighting Lion if you have it.
i uploaded a video and linked it for a demonstration doing A Garden World
i tried that already too it just doesnt give any progress on the quest
I ONLY got credit on the corrupted strike. That is why we formed a team and bailed on the strike and went to the blind well. There you can farm the hell out of kills. I got no credits from anything else as far as I can remember.
Then, something is wrong. If you were on Xbox I would run it with you just so you could get the gun. I ran FL and some bs genade launcher in the power slot. But, there have been more issues with things not being credited lately and the lag is getting really bad on xbox. Make a video as that will at least give you something to fall back on as far as credibility...hard to dispute video evidence.
