If you expect more then 1 gold you'll often be dissapointed 4 golds is a good pull - ultimately my expectations are 'I want a gold' anything less is a bad pull, 2 is a nice pull 3+ or a 6* is a good pull
Well, I always hope for a 6*, but getting new golds is always a good thing. But then, getting a new+dupe on the same pull, that's a first for me...
edit: I hope they don't get smart and change the boat race results
