It would be a nice option to double the rewards from maps with using two maps at same time. Or triple the rewards by using 3 at the same time. Players that do not like this option of course have the normal option of doing one map, available.
It could cost 4 maps, playing 2 maps at same time. or cost 6 maps doing 3 maps at the same time.
I just find maps too time consuming(compared to rewards) by only have the option doing one map at a time, and that is why I never do them, and I think more middle game players as well as endgame players would have played teasure hunt more frequently if we had this option.
What do you say?
