While I haven't tested it myself yet, I think Focused Defence would definitely have its uses in PVP. For one, it is only usable if stunned, so when you've already used your CC break and are getting focused down while stunned, instead of siting there and taking a pounding, you can now reduce the incoming dmg (DMG + sml heal = reduced dmg). Once you have endured the stun you start up your rotation again to build focus (as though you have just started the match). I haven't tested how fast your focus is drained though to see if it is truly viable yet, so dont take what I say to heart. Just a thought... Edit: and I'm speaking from a Focus Guardian point of view here too, and seeing as the skill Through Peace is in the Focus tree, this would lean me towards it being good for a Focus and PVP build. I can see its uses in PVE as a DPS Guardian when you draw aggro off a tank and get stunned. But hey, I could be wrong...

1. The companion mission return box can now be toggled off when in WZ's. Its in your Preferences, but cant remember where as the server is still down. 2. Haven't really trialed this to see if it is fixed as after I realised slicing (lockbox) was broken, I stopped wasting money.
