So a strange thing happened to me today. I only play this on my iPad but I have it on my iPhone to get rubicons for watching the ads. My iPad is set to manually update but my iPhone is set to auto update apps. You can see where this is going. My iPhone now has the updated version but my iPad has the previous version. The prices are different on each version but it appears that I can choose to buy DotD or heroes pre or post update prices depending on which device I use. So, before this gets fixed, which version should I finish the hard campaign on to get the best rewards? (I only have two stages left before I finish the hard campaign).
