Should have given an optional alert toggle for merging 3 items(by rarity), coz when u played a long time, you saved up 5 really rare thing(say epic or legendary) and then there are too many factors that would make you accidentally merging just 3 of them....... then you will go really angry and throw your iPad away for 2 days.... the game itself is pretty good, but has a lot to improve. Say I have 6x wonder#10 and 4x wonder#3, I can’t merge them, it doesn’t say what’s them for in the game, then I’m so confused and don’t know what to do next, it’s eating up my land, they took me hundreds of hours game play to achieve, then they’re killing the game play experience.
