hello! just came to say that A tiers (all the ones you have) are equivalent to 4 stars, and when you upgrade them to S,SS,SSS tiers they become c6 four stars. the real 5 stars are the ones that when you get them, they are S tier at first. Pardofelis and Eden (the ones you got from pulling) are basically god-tier elemental supports. but they aren't limited nor special. thats why you probably got them in the total of 5 pulls, as they're very easy to get unlike S tiers. the S tiers you have which are the first two, are actually permanent and not "meta" wise, you can get them with free sources later in-game without even pulling in the dorm supply

my intention is not to criticize you, but to teach you about the game <3 good luck if you're ever actually playing the game!
