This week I got lucky, one of the weapon is glaive, so enter DA and EDA, with random PUG, and have a success in one try, got some so so reward and a sumdali.
the funny thing is, after that I play Regular Netracell solo, first I got a Tauforge shard, second time I got A melee duplicate.
The conclusion is, The RNG of reward in DA and EDA is weird.
