Dark Souls had amazing animations for example.
Like when you stood on a pile of rubble, your feet and legs and standing posture accommodated for the varied terrain. Like one foot would bend to be angled to be flat, and my knee would prop up for balance. On top of that it wasn't 15 preset standing poses, you could dynamically and slowly walk over the whole pile and it would follow. Weapons would glance off of walls with a reflex and a satisfying ting and recoil. Larger weapons would have to build some amount of momentum before they swung, and they would thud into the ground with some weight/ recoil. Rolling animations changed based on your carrying weight. Like if you had a lot of gear on you, you would do a flop to the ground and struggle to stand back up as you saw your character fighting for balance. Your shields would blow back with a varied amount of feedback based off of % of health lost in attack and % blocked.
This is an MMO however, so please don't try and add this level of detail. I don't mind bad animations when I know that they aren't good because they are improving overall game performance. If I could have this game have Morrowind graphics/ animations, but run smooth as silk, I would throw out all the high end settings out the window.
