Primal vs Primal ??!! eg, Shvia vs Ifrit

My impression was that there was going to be one of each type per world. Which would mean a full set per world. Having just one summon per world would piss me (and I'm sure many others) off, and honestly would, imo, screw up the lore.

OP: I believe that it will be possible, as players will be able to summon them for certain events. And if you're in a LS vs LS type setting, perhaps both sides can summon their primals, as long as they have them.
