So I grind my rear off to 70 after taking a break for a couple months. I am all excited to gear out at max level relics, so I pop my extreme fortune.
First 5 runs I get a whole whooping 4 relics at 110 Fate each run. That includes hour glass, don't die, none of it mattered.
So I unlock the extreme card and try it with another extreme fortune. (Now admittedly I failed one due to not paying attention and getting caught in the crossfire of the psyker that splits into three and not being able to get out.) In four completed runs I got a signum on one handed weapons run, and a sniper rifle on an armor run. There was no noticeable difference despite the supposed chance to double my drop rate and the 50% chance for drop card. Two just gave me a few purples and two greens.
Now I do understand the need to slightly nerf the drop rate with extreme fortune. Most of us threw on the timer and did assassination runs till we were blue in the face for an outrageous amount of relics per run if you got lucky to find the splitting psyker. (three per assassination, one in the chest, one per psyker, and up to 5 in your final box.)
However, this is insanely ridiculous. I have wasted 1100 fate, two extreme fortunes, and I ended up buying 5 relics to gear from the dlc arsenal. I could have bought another xpac for that.
