For the first time I decided to dedicate some extended time to only doing the 10 rounds per run on Onslaught and on wave 6 I had a Necrophage Drop (which is the echos trace rifle) and I also had a echoes glove drop on our final round so anyone that doesnt wanna do 50 rounds over and over...you can get echos gear from the 10 rounds so hopefully this helps some and I will run a few more tests and have tonics going with them and see if it helps with the drop rate...seeing as you can specify kinetic/Power etc etc. Anyone else that has info on this plz share here. I've used tonics on 50 round runs and its been about 50/50 on having 3-4 echos gear per 50 rounds or none at all lol
