I can see the thought process that went into making that, but I doubt that would work on 720p.

As it is, I have issues with targeting larger mobs, because if the top half of the mob is off screen, the game WILL NOT tab-target the enemy, At All.

So moving your character's feet up cuts off the viewing area above your character, which means that tall enemies will go off-screen forcing me to click-target them which is a PITA in any fight that has adds because it can cause multiple GCD loss in trying to find the thing to click on it, sometimes I click and I get a party member that's standing next to it, etc. Unless I tilt the camera way down... then I can't see the area near my feet very well to avoid AoEs.

TBH, I really wish they'd fix the tab-target problem; I don't understand why the top half of the enemy has to be in view for you to target it. I don't get why you can't target it as long as its hitbox circle is within view.
