Are you running out of Gunner (yellow) Evo 1* runes and Sentinel (green) Evo 2* runes? Where are the best places to farm for them?
Well, I had some spare Ironite, run each and every BnW dungeon, and here are the results.
Of course, this isn't a proper statistic, which would require thousands of runs on each stage. But I am neither made of money, and don't have the nifty 10x speed the devs enjoy, so that's the best I could do.
Let me know if you want to see any changes on the layout, or to test any other stage, even beyond BnW.
