I hate stars....I never get any luck with upgrades - after playing Thunder of Zeus server since day one I only have 2 heroes over six stars!!!! I would like to make a suggestion that the development team introduce the same method of improving the chances of a star upgrade as they have with sanctifications. if you like this idea please post your approval and see if "Team Tynon" take any notice.....just don't hold your breath, but here's hoping.
