well, yeah, of course you're going to farm more fine tins that sup ores, but have you been following the thing carefully? what i've been doing was binding 10X timescale, 999 mine bombs, 1k movement speed, and 0.1 sec mine bomb detonation to a key, and farming that map. i can usually farm that map in less than 5 seconds, with the map reload and etc. farmed about 200 fine tins and 80 sup irons in a about 10 mins.
also, you are on the 2nd map of fruitful, right?
