Take any unit that is on a horse/warg and watch the counter-attack animation. Where is it you ask? I don't know exactly, except that it is about 7 seconds in the future. If, while mounted, I kill a unit in one blow: no problem. But if I strike, or even worse, if I am the target of an attack that does not kill me, an eternity passes while I sit upon my trusted steed. Please deliver me from this agony!!!
