Be nice if they gave us guard back but slightly different.

Guard: hide behind your shield but lose the ability to attack or perform actions. % blocked varies with STR. Effect fades upon reuse. Recast :00.

This could be usefull for tanking multiple enemies or for enemies that hit extremely hard. You wouldn't use it in a general situation but it would make PLD feel more specialized in the art of the shield. Make us feel like we have more control over the damage we take. You can gain some emnity then hide behind your shield then when you feel emnity may shift you can drop shield and gain more emnity.

Better shield proc rate would be great as another option too.
