If you just started, pulling from the FF collab is a pretty awful idea. There are some powerful leaders in there (you haven't gotten any of them) but generally speaking collabs should only be for veteran players that already have deep boxes of the pantheon gods and God Fest exclusive cards.
When you're just starting out from scratch what you want to do is wait until a God Fest (they come around at the middle and end of each month typically) and then delete your account to "reroll" your very first free pull on the egg machine. Do that over and over again until you get a top tier leader. THEN start saving up your stones and ONLY pull on God Fests. Only, only ONLY, pull on God Fests. This is the #1 golden rule that every PAD player will tell you. All of the pulling you've done on FF so far has been basically a waste of your free stones because none of those cards are going to bolster an early-mid game team.
If you absolutely have to have FF cards then by all means go ahead and pull them, but they aren't helping you at all. At the very least you're going to want to at least reroll your account until you get a good one of those. The ones you have gotten are pretty bad. You're going to want to reroll until you get a powerful leader like Noctis, Yuna, Tifa, etc.
Again, I don't think I can reiterate enough tho, that pulling FF, or any collab when you start is bad.
