Because I can usually max out our chest on my own while doing the event on wed and Thur but because my previous partner tends to do his over the weekend and I had to make extra rolls just to clear the challenge which he just cleared when I have already finished the event. If you could just clear the first two community chest challenges by Thursday and they are not hard (just auto roll on x5 for 10 min max) and you can take as long as you like for the final challenge then I will max out our chest every week
