I have around 30 completions for VoG. Weapon wise I've gotten;
3 vex
2 fate bringers
5 atheon epilogue
2 VOC
5 predict revenge
3 corrective measures
1 pread time peace
2 Hezen vengeance
The only thing I don't have yet is the foil
Note: just an FYI if you didn't know the vex only drops on hard mode
Edit: for me the hardest to get was fate bringer I only got my first one about 3 weeks ago
