I've heard ppl say on forums that they have been warned by GM's about it. But have also seen videos of ppl doing it in nearly every zone and they have never got in trouble for it.
Either way im sure you wouldnt get any more than a warning for it
Nothing will happen as long as no one GMs you for being pussy hurt you got to the NM first. Do as many VNMs you can until they patch this ***with draw-in.
The thing I see about pinning a mob, there really isn't a way around it (from the developers standpoint). Rescripting a mob's pathing to continue around an obstacle would give a greater advantage to the players who have movement speed. Considering the relative ease of acquiring that, SE wouldn't go for it. The only other option from SE's side would be to make mobs ethereal, and much akin to them being able to climb impossible heights to reach players, make them now walk through walls and such.
Just told us we had 30 minutes to kill it before s/he did something about it.
QFT. The most GMs can do is ask you to kill the NM.
@above poster: most vnms have +25% movement speed (some +50%), so kiting would be impossible unless you're using Clipper or something.
