Casting spells not possible in mounted combat? That's pretty weak for a big game developer like Bethesda.
Perhaps they should had waited with the mounted combat and put it in a DLC insted if that was the problem that it was going to be free.
I can see their conversation going on like this
"Hey dude, why don't we add first person view and let players be able to use Bound Bow or cast fire spells if they want when riding their horse?"
"No, are you insain?"
"What?"
"That would take at least 6 more working hours, we don't [censored] money!"
"Oh yeah, I forgot. This is a free update, of course!".
