Moving NPCs by pushing them (running + jumping) is too effective
In Vanilla Morrowind static NPCs were very difficult to reposition by "pushing them".
To push an NPC you need to run in their direction.
NPCs have an idle animation in which they move their feet every couple of seconds.
If you are running towards them, they will be moved by a very small distance.
If you are running towards them and you jump, you will slide, sometimes jumping over their head.
When you run towards an NPC and spam the Jump key, you can quickly push them in a specific direction.
You could push a vendor behind a corner and steal items from their shop, or push someone off a cliff.
I think the behaviour currently present in OpenMW can be useful if you are stuck in a tight corner, blocked by NPCs.
However, it can also be exploited to move people to a desirable spot, and leave them there.
The "weight" stat is not taken into account either. Even a wood elf can easily push an orc.
BTW: You can quickly push NPCs, even if they are overencumbered, and they can't move on their own.
I wonder if the following solution would be possible:
Patrolling/escorted NPCs would walk back/move away when pushed by the player.
Static NPCs would move back to their spawn point, after a short time, when pushed by the player.
