I dont really undertsand … how many eggs shall i open just to get a good Legendary … i spent alot of money just on buying gems … this is so annoying 
How many have you done? Have you done them 10 at once?
Ya man, unless you’re spending 50 gems at a time at a guaranteed festival on a guaranteed roll, you will be disappointed.
Otherwise you’re just gambling. Which , don’t get me wrong can be fun, but your odds are 4%. Don’t be mad when the 96% comes to pass.
