Increase the range a mob let himself be pulled + mob linking.

The current distance is far enough. Any farther and its back to ffxi sit-in-one-spot-all-night parties. No thanks.

Mobs are not clustered nearly enough for that. Roaming parties will always be preferred regardless as to how far you can pull them.

@OP I agree some mobs may need to have their distance extended some but double and triple would be a little too far. You also have to consider the complaints from people who can't get away from an aggroing mob because it followed them too far due to the change.

I do agree though that certain mobs should link. I really haven't noticed much, if any linking in this game. It's pretty much just all sight aggro with a few sound & sight aggroing mobs.
