The cyborg dungeon for BHE isnt any longer of a grind than the ferryman was, after the frag drop rate change. It took about 1500 ironite for the ed, but the rewards are not as nice as the ferryman.
The BNW event is as easy as they come, mostly common talis needed. If you dont have them, a short grind will earn them. If you go with the lower tier battles the time it takes to change talisman is longer than the overall event.
