Focus on the rares, there's always some up. I have done normal like 200 times and gotten close to 15 pets, 1 mount, 1 toy and a bunch on quest. What I normally do is I do my minimum needed on my main and then I focus on the alts using the island expeditions for leveling. It's not the best use for leveling even with well rested, but I focus on the rares and invasions, an I get 2 things for the price of one.
