Ive been stumped in my weekly challenge AGAIN because I need to complete the whirlwind which requires four players to coop. Problem is I play the game with one friend and dont have enough friends on my list to complete this nor do I want to add any - as I stated ages ago when weekly challenges started. Would it be so difficult to require an alternative to the co-ops in the weekly challenge. Mind you considering the mess things are in with the game (excessive zone refreshes , for example, are making adventures difficult to play correctly) I'm probably asking too much.
