To stay on topic. I'm pretty excited about their "large-scale" additions to Fields of Valor. I have yet to try out Maze Mongers but I'm sure they'll add more worthwhile items. So far all I really see out of it is that sword that BLUs drool over.
As far as battle adjustments go, I'd be happy with fixing up Astral Burning and eliminating "curegasm" altogether. I'm sure you all remember being frozen still until the casting animation was completely finished as you engaged or disengaged. Unfortunately it still applies to every other spell other than cures.
