An Idea for Focus Target and Assist.

[Eruantien]

Uh... I just set a focus target by hitting square while targeting something then selecting it from the list. It's not hard at all.

If you want to use potions I'd just practice making an extra bar that you swap to manually. I have an all-purpose bar with potions/ethers on it as well as limit break/sprint/mounts that works fine.

Ahh square is the default. Like I said but square.
