Really its all relative to strength. You and I, with our full 6* line and strong allies, its a cakewalk, but for weaker players 12-# can be a meat grinder until a much later level. 10-3, while nowhere close to 12-# in rewards, is a good and easy way to farm leveled manyus if nothing else. I do agree the 12 stamina SG with 2-1 is essential for early players though.
