I think that funcom just needs to make it easier for only one monster to pull...
like if your in a huge mission room and you attack one mob and theres another all the way across the room, usally he is going to attack...

actually there has been a better chance of pulling only one mob latly. but i think that it still needs to be worked on...

also in a little respect for funcom i dont think we should whine too bad or maybe they will bring back chain healing mobs...

remember how fun that was? lol
