It takes at least 5800 ironite to "collect" the Edd this current method without "luck" involved. It took 3630 for me to gather the frags necessary for Scrooge. The Scrooge event was cheaper on ironite, but the grind is mind numbing. As far as Yup's situation with Gunner Ghost, I would be and have been pissed and disappointed in the past. They will chalk it up to RNG, but I think something can be done to address that. What I did was save enough frags for 3 souls and dropped them at the same time. Got 2 Sentinel and 1 Gunner so it worked out.
