Mob Levels

That's cheating! >:-O

Kidding, but I agree with your post. I'd like to add that there's a third type of aggro, called alternately "true sound" or "scent", where walking will only halve the detection radius, rather than eliminate it. Mobs with this aggro type include, most annoyingly, boars.

For these you either need to run by on chocobo and pray, wait for them to move out of the way, or use Wrist Flick to stun them and then hope you can get far enough past them after they recover.

Might as well mention that there is a small chance to evade even these high-level mobs. I managed to dodge an attack from a L70 boar on my way to... Longroot, I think, as a 21CUL.

Alternatively if you have Paladin just pop Hallowed Ground and jump on your chocobo to get through some of the more unforgiving parts.
