Guild Wars 2

Thx for your answers but 2 more question:
1.Is precision/vitality/healing power gear worth it?, some people say healing power isn’t worth
2.If i go with knight gear and soldier runes, what jewelry and weapons should i use?

I have a altruistic healing build:
http://www.gw2build.com/builds/simulator.php#1.3.11.7.0.0.0.0.0.0.54.66.67.65.77.0.0.0.0.0.0.0.0.0.185.186.191.197.203.204.212.0.0.0.0.30.30.10

About gear i have enough karma for orr set with this stats:
Power/vitality/toughness
And a full berserker jewelry set with berserker weapons

What i want to archive is a support guardian with great survival
1.Is this good gear for that
2.What runes and sigils should i use?

I made this build for damage/support
i use great sword for aoe and sword/torch for single target
what i want is good damage and average support/ survival
my equipment should be power/vitality/toughness or other?
