I prefer a wider range of content types, or a more even spread.
The reductions to one dungeon per patch is absolutely fine by me, if it means we get more in the way of other content.
We have had that this expansion to a degree, with an additional different type of Trial (Memoria Misery) and Bozja's Castrum (pretty much a fourth Ivalice raid) however Varis wasn't a great implementation of that in my opinion, and while I think Castrum is great, Bozja as a whole isn't really a net gain seeing as we lost a deep dungeon for it.
But it seems to me that the 'extra content' is probably always going to be a bit experimental and therefore hit or miss for many people.
