Auto Attacking?
Definitely leave it on. Other skills you activate will override it or you can just cancel the chain, and it’s mindless damage. Plus a lot of builds use autoattack as one of the main damage sources.
Ranger sword being a notable exception, leave it on.
In pvp if you are a projectile user and eating lots of reflect, you might choose to turn it off.
For the elementalists’ weapon conjures all the AA are turned off.
In wvw if I get into a golem I turn it on.
There are a few exceptions where moving your auto skill to a utility can be useful. Mostly in PvE. Otherwise I say keep it on 1.

In some burst builds, You don’t want to be wasting your +x% damage modifiers on your auto attacks either, so in those situations, you would leave it off.
