Disable L3 lockon

[StouterTaru]

There is a very limited number of things you can assign to those two buttons, or you can calibrate the gamepad and choose skip when you get to that button to get rid of it completely.

I don't know anyone who uses lock on anyway outside of lazy mode autorun lockon to a friend and follow them through a dungeon while you grab a drink from the fridge...

It is used to properly strafe without missing auto attacks, which is a considerable portion of your DPS for melee-range jobs.

EDIT: To reply to your most recent post, while your executed skills make it to the target, your auto attacks do not.

Also the only time it would be faster to get to the flank from the back and vice versa when not locked on is on huge bosses and that is also only if you are someone that goes all the way to the flank/back rather than the edge. The back starts where the circle under the enemy ends and the flank starts where the circle begins near the back. If you stick near that edge positionals will generally be decently faster

Don't make travel time longer that it needs to be.

I use it on melee
On ranged I use it during LB3 so I can't accidentally miss (since it can completely miss if you aren't careful).
