i like floating damge numbers but not in skyrim
This.
In most games that have it, I don't mind it (they're generally more toward the "action/arcade" side of things).
And I don't really get this whole "immurshun" thing people keep throwing around.... based on the various vague non-definitions I keep seeing, I've never been immersed anyway. :shrug:
But I still think floating damage numbers wouldn't fit in TES.

(You know what I'd love? A combat log of some kind, presumably hidden in the menus, so that I could look and see what actually I'm doing in combat and what techniques are effective. But not if it was intrusive in any way - not running in a window as part of the UI, but tucked away.)
