Legendary catch rates

Ok I re-downloaded this game because my friend told me legendaries were being released in raid battles. Little did I know that they are nearly impossible to get. Ive done and completed at least 6 legendary battles on daily raid passes and havent gotten 1 legendary. Niantic really needs to fix the percentages of catching these things because as of right now, they are only good for xp and wasting raid passes
