Then if you use up/down on d-pad to choose the Tank, for example, you can then press assist and have his target selected.
This also works the other way, so when targeting the mob, press assist and you will now be targeting the player the mob is attacking, so you can throw on some heals.
Useful in FATE's to keep the Tank alive if he's not in your party.
And a double tap on assist can change your targeted mob when the tank changes his target.
