Primal ex are going to turn into FATEs at some point with a claim system maybe? As it is at the moment no one that have lev access do Garuda Titan and Ifrit ex unless they helping FC member. Putting the ex as a FATE will make them relivent again. Will be similar to what we saw in the benchmark against Ifrit. I think SE do this with all primels after they been out for some time, and 2.3 - 3.0 we will see the first installment of this to tie in too FC primels summoning.
