In addition to some of the better proposed solutions... I'm waiting for them to make mob aggro work more like it does in FFXI and less like it does in WoW where if you get in the mobs radius it will aggro. However, I am glad that they stuck to the part that if a mob is TW it doesn't aggro you. (At least I hope I did. I didn't run into too many mobs that aggro at my level...)Moving on to the FFXI mob aggro types!

Sight
Sound
Magic
Low HP
or all of the above, or combination of the above. For example. Undead in FFXI aggro Low HP and Sound.

Certain mobs can be avoided if you do not get within their field of vision aka sight aggro mobs.

Also, some mobs will aggro but not link. Again, Undead reference. Skeletons aggro but not link.

But I think you get the idea.

They also need to stop pairing up mobs when they spawn. Every time I do a leave quest it's always me x 2 mobs or x3 mobs. It gets bad. As a PGL I'm squishy and I don't have a great means of keeping up HP without tapping into my rather piddly MP.

In any case. They really should implement that aspect of FFXI's mob behavior.
