How about adding a second Primal Focus Quest?

[ChriZirhC]

The thing is when the Primal Focus quest was introduced all the first 3 ex primals were released at the same time. Doing it right now doesnt pose as a challenge since we're overgeared now for the new primals(excluding shiva). What they should have probably done if they wanted is just stick to the 4man story mode primals, current ex shiva, ramuh and levi would be hard mode and then release a harder ex version of them on a later patch(maybe 2.5) together with the new primal focus quest.

Nah, what they should do is add Savage(?) versions of each of the primals and give a high level rewards for beating them all.
Though I'd imagine they'd do that for the expansion since it's hard to justify making them any harder than they already are aside from things like reducing the number of orbs that spawn at any given time during Ramuh, having them inflict damage when touched, having Good King Moggle Mog blast players for the amount of damage left on the moogles when he heals them, Levi spawning adds during dives...
...i'm gonna stop before i give SE more horrible ideas.
