Mostly only 2-1. I did run a lot of ?-4 of the event but that doesnt give manyus, would explain my excess gold. You could probably run 1-3 to. Last few days I've been doing some 2-1 and some 12-4 since I've been trying to get better equipment. about equal stam of both i'd say.
1-3 has 3 chests same as 2-1 but costs 3 less stamina
I assume the odds of getting something other then a 2* is the same....so why 2-1 over 1-3?
