An Incoming Cygnus Knight Revamp?

The reason I rarely use Restoration on my Paladin is because it just takes too long to cast. When fighting any boss that matters (IE, that can do damage, mostly through 1/1ing), by the time Restoration is completed, I've taken another 1/1 hit. This is very apparent whenever I am doing Zakum. I spent time using Restoration, and by the time I regain control of my character, I've been 1/1ed again. It defeats the purpose of bothering to use the skill at all. Potions take almost no time, and certainly don't completely disable your character.

Does it really matter? With Power Guard on, it takes about 5 1/1 attacks in a row before you're even close to the point where Zakum can kill you. It's not too difficult to do an HP pot-less Zakum solo at that level with Restoration.
