Yea I mean I don't know I just felt it was something to suggest but these are all good points. Honestly my goal was to mainly find out if I was the only one who had issues with it. Though like some people have said there is the issue with the emotes. How it would drastically change the game like you pointed out.
Mostly though I see more positive things that could come from this. One example that comes to my mind is pets can move past you to attack so you don't have to adjust where to attack npcs from an area. Mostly I've had issues with it post lvl 50 where you have some missions that have a hot door and due to threat detection from npcs, I have gotten pushed into the barrier which then makes me the first target. Half the time I am definately not the person to want to be the first hit and collaspse on the floor.
