More Descriptions In Combat, Please

I think our combat in D&D could use a little more description of what's being done, particularly what the NPC's are doing. I know we don't need to know the flavour text of the battle, but it helps me role-play, and draws people into the fight.

There are times when I have no idea what our opponents are doing other than attacking us. I'd like to know if they're breathing fire or whatever.
