I know that campaign stars are only rewarded in these fights: Events, Story, PvP, Explore (Difficulty IV+), Delves and Pet Rescues.
What I want to know is WHY only these fights. Why not Daily, Underspire or Arena? Does anyone know?
I’m wondering because I like to play Arena a lot and I haven’t been getting stars from it. I may have to play Explore just so I can get the stars I need because I don’t like PvP.
Edit: I now just completed a campaign task in Arena (favored enemy), so why doesn’t it reward stars as well?
