I think there's not a lot of reason to have both the extra Guard LV when Guarding and the doubled Armor when Guarding perks. I think it'd be better to keep to the Block effect and change Perseverance to something else, such as:

Perserverence (5 Ranks) - Increases Status Resistance by SR * 2% when using a Shield. Doubled when Guarding.
