You are forgetting the 2 up top as well mate. Without getting those two as well you will not clear the map.

Yes but to get that secret garden you need to spend more stam and hope for the best. So what i'm interested in is which is better based on stam used?
Say you have 240 stam that is 3 runs of the daily vs 2 'possible' secret gardens... now you get to do that about 2 times during the space of 1 day so it's 6 runs of the daily vs 2-4 secret gardens (most likely chance to only get 2 when done in 2 x 240 stam hits).
That was my reasons for doing the dailies. Slightly less chance for lvl 100s per run but with 6 runs that is 18-24 chests vs 6-8 (12-16 if you get really lucky and spawn 4 gardens but that is like 1 in a million) for the same stam.
