We talk about favorite Guardian builds

I use the Healway build originally introduced here: WvW/PvE The "Healway" Guardian. That post is mostly gone and the thread is locked because apparently the guy that posted it wants to be able to do something other than discuss his build all day for some reason.

Here are the specifics at GW2Buildcraft

The creator made a bunch of videos of it in action also: ChrisDawnheart on YouTube

The gist of it is this: you give up critical hits (and altruistic healing, which is somewhat blasphemous) in favor of strong and long-lasting boons. I was really skeptical of this build at first since healing power appears to scale so terribly, but in practice it works amazingly well. Most of your damage comes from retaliation which is up pretty much 100% of the time, ignores armor, and can't crit anyway. You can absorb crazy amounts of damage with this build, so the playstyle amounts to running around trying to get hit, which on this server is pretty easy.

The beauty of this build is that, while it takes advantage of much of what a guardian can do for a group, it's equally great when you're alone. A lot of classes favor builds and weapons that hit fast (thieves, warriors, rangers, engineers especially), and often they'll melt themselves on retaliation before they realize what's going on. You can survive the worst that most burst builds do, and have pretty good condition removal, though really persistent conditions (particularly poison) are one of the places this build can run into trouble. The main problem is that you'll stalemate against other bunker builds, which can be annoying.  But it's better than dying.

A few other points:

• I use a hammer instead of the greatsword recommended by the build. That's a playstyle thing mostly, but the hammer is amazing for WvW. 3 forms of very nasty crowd control, a blast finisher on a 4-second recharge, and light field giving protection on every third autoattack (=more retaliation for you and everyone around).  I also use mace/shield as the other set, though the shield is the important part.  If you're fast, Shield of Absorption knocks everyone out of a thief's shadow refuge.  Since they use that when they're already in trouble, this often lets you finish them off where you otherwise would have lost them.
• Stand Your Ground is absurdly powerful -- over 7 seconds of group stability and retaliation with this build. It basically kills that dagger storming thief that spins into our zerg with one button.
• With this build, shelter not only stops all incoming damage the instant you hit it but it's also a very solid heal. That, plus renewed focus gives you a good amount of time to get out of a bad situation.
• Selfless Daring scales very well with healing power, and a lot of the gear choices are about making dodge rolls more readily available. This give quite a bit of on-demand healing to you and whoever's around.
• I generally slot Retreat in place of Hold the Line when running around a lot, which is most of the time. 30 seconds of group swiftness at a time is just too much of a creature comfort to pass up. That plus Save Yourselves gives permanent swiftness without equipping a staff.
• I wouldn't suggest this build until you're ready to do it with exotics. The gear really makes it work -- particularly the boon duration runes. I'd advise previewing it in the Heart of the Mists before making the commitment.

This is my "All round build" Wanted a Tanky Dps guardian, and this is what i came up with.
I'm in WvW often and this build helps me get in close, do damage, drop some people then get out before im seriously hurt. I can solo with this build but it is not preferred. It has an excellent mix of survivability and dmg (in my opinion) and excels in wvw. keeping aegis up will allow you to do more dmg to your targets, or swap it out for vengeful and make your retaliation last "that much" longer. With Altruistic healing, i can keep my health bar full and help the team. Running shouts helps with those heals too, so on top of shouts being extremely useful, they'll heal you if you stick close to the team. I never wanted to be a support guardian. so this is as close to support as im willing to go.

IMO this is a well rounded build, that'll keep you alive long enough in the thick of battle to drop some of those SF/ET kid's and then get your ass out of their while the zerg wonders why your health keeps going back up.

my epic balls to the wall build
0/5/30/30/5
Free blinds and might on F1 so awesome possom
Got about 1.7k power with 30% crit chance and 55% crit damage
Runin' with full clerics gear and zerker's weapons, amulet, and 1 ring.
Goooood damage and immortalness granted by the healing, running with food that gives more Healing power from tough/vit gives effective 1.25k healing power which is insane if you have a buddy casting regen on you (I.E. ENGINEER HEALING TURRET)
using hammer/greatsword for mass CC and good dps as well. GS has sigil of life hammer has sigil of intelligence (accuracy works too but I love swapping then hitting crits 100% with the hammer blast)

runnin' full shouts with pure of voice trait and runes of the soldier (2 condi removal on SAVE YOURSELF and STAND YOUR GROUND, 3 condi removal on HOLD THE LINE [bugged])
elite is obv the 90s cd one whatever that is
this build gives you a shitload of ways to counter almost all builds, so if you understand what the fuck your enemy is doing you will never, ever, ever die except to maybe dps mesmers.. there are some classes you cant kill like elementalists or bunker guardians.

edit: you are also the stomping master: cast well-timed aegis to stop their 2 skills, f1 to blind them when they use it, or use stand your ground for a guranteed stomp if youre in the middle of a group.
