I've just done Split City Fall.
I got about 615 K xp and my guild mate got about 380 K xp.
It's a big difference between the two of us.
I didn't had premium friend buff or scouting on while playing. So that doesn't explain the big difference. Our gens are almost same skilled so that wouldn't make a diffence to.
I was the one completing the tasks.
So i think only i got rewarded the xp for completing the tasks.
But i guess this should be for both parties in the adventure cause we are in a co-op?
