My build is gone?
Something like this might work for you: http://gw2skills.net/editor/?vVAQNApeWl8Ah6hYnQwfHwPEHJEFeDeuU4usBwBknh/rEA-TpQWABOWGAg9HAA
Since Guardians have natively high toughness, going for high health may prove to be a good idea, especially with tons of blocks and ways to heal yourself when things get hairy. The amulet provides you with crit so that you can proc all the crit based traits that give boons to you and allies which will also heal you for the boons applied. Check it out, see if you like it, tweak as you desire.
