Please don't get me wrong but those fights are perfect the way they are, They make it so you have to learn the job. Find a summoner on your server who has done them and ask for tips, SE doesn't need to change the difficulty level of those fights, its not like you need the best of the best gear, when i did mine i was in with only spell interruption gear and i didn't have astrals which are useless in that fight anyways.
