It's kind of hard to watch animations of mobs at higher ranks. I'm usually killing things in groups for sp, and, unfortunately, like another game I won't mention, too much happens all at once in battles. The mob is usually overwritten by graphics from being hit, nuked, debuffed, weaponskilled, shot with arrows, etc. A lot of the mobs seem generally smaller in scale, too, compared to some FFXI mobs. I've seen the imp animation, but they're so small in scale, that I had to get up close to it, and zoom the camera in all the way to really see it (and I play on a 27" monitor).
There was one mob I fought that entertained me. The Ogre in Mor Dhona. It turned it's head, and not so much it's body, and looked down on me. It watched me walk around him for a few seconds before he turned to face me and prompty knocked me to the ground. I do believe the Ogre is my most favorite looking mob in the game so far.
