What would casual gamers like to see with regard to 'battle' content?

Major improvements should be made to hunts, and FATEs. The advantage overworld gameplay has over other instances is that it comes prepackaged with an expansion launch, the barrier to entry is incredibly low, and they have the potential stick around long after. I want to make a big overworld improvement wishlist post one day.

Oh God, please!

I don't know if it's your idea but making every overworld have a few FATEs like the ones on Bozja would already be a massive improvement!!
(I think they're called skirmish, the ones we have to register and teleport).
