I still have 1.6 units of faith about that patch...
I can't speak for other modders, but I'm unlikely to put any efforts into this unless it becomes obvious 1.6 isn't happening.
Same had said for FE 1.4. Well, do we have 1.4 FE?
I am pretty sure Stardock is pretty much moved on from LH for new Elemental and Galciv 3.
