I went broke trying to get all the presents I needed and I have lots of explorers. That being said, I am happy with what I got. I upgraded the market instead of getting the GB houses, there was just no way to get them too. I upgraded my market to lvl 4 and I am very pleased, I was struggling to keep up with resources since the weeklies were introduced. The tree presents at my level are meh. I don't want to run adventures for presents, but if there was another way to get them it would be good. Or otherwise, don't offer soooo many things to get in merchant
