Question in line with: The Double EXP Campaign! (01/30/2013)

[Karah]

Well they could do something like make the conquest points or Imperial standing modified to gain 20% instead of 10% that would benefit players who don't need xp or limit points

That -is- what they're doing, indirectly. By gaining double the exp in the zone, you will get double the AN IS or CP

[Mirathil]

It wouldn't be Square-Enix without unnecessary restrictions.
Basically, all of the ways people EXP these days this event doesn't apply to.
Even if you were to try to take advantage of this event, you'd still gain less EXP than you would from current methods.
