2% chance of a 5 star. Im 150 epic summons in and havent got one. The sympathy one u get every 85 summons doesnt count either. By your maths you should approximately get 1 every 50 summons. I should have 3 and i have 0. This is garbage. This is worse then empires and puzzles and thats saying something as they have terrible odds but at least their percentages do work.
