Ive noticed from every single rune chest i always get the lowest rune possible. This is not an exaggeration, ive been playing for 5 years and ive never once recieved any rune that is higher then the lowest rune lvl in a chest. For example, on 16 1-2 chests i open all of them are lvl1 runes. On a 5-10 chest that i saved up to open 10 of them at once, i only recieved all level 5 runes. Please increase the % for higher tier items, its bad enough you make the game dam near impossible to play free, but chill on the pay to win stuff, or i will be deleting this game
