Never use sword with my guardian. Standard hammer and staff Ah build here. I haven't moved from it though as it worked well for dungeons. Care to share why a sword is viable?
TBH all Guardian weapons are good. You can pretty much go for whatever you want. I've got a full set of exotic weapons in my inventory at all times and I just switch to whatever I fancy doing.
Running a AH build you aren't really specialised into any particular weapon set, so you can just switch up as needed.
I tend to avoid Greatswords because they are
soooo cliché! Everyone and their mother runs greatswords because BIG SWORD!
Hammer is great fun on Guardian, I tend to use that a lot too. I have a
Magmaton for such situations
Hammer is worth using just for Skill 4 (Banish), there's nothing more hillarious than launching your enemy half way across the map with a huge hammer uppercut
Plus the skill 2 blast finisher is great for spamming retaliation on your team.
Mace + Shield has epic tanking ability, with fast refresh blocks, the heal on auto attack 3, extra toughness from shield, protection, and the shield bubble/heal. Good for going toe to toe with tough enemies and keeping your team up.
Scepter has suprisingly good DPS for a ranged weapon, if you can land your hits it's actually the highest dps ranged weapon in the game (using auto attack and skill 2 smite), it's just let down by the slow projectile speed that's easy to dodge. But for PvE when enemies tend to stay still it's a good choice.
Staff is a super support weapon, but I find it better for WvW, party speed buffs, line of warding, and party wide might (which doubles as a big heal when running AH) works a treat.
Sword is the highest dps weapon available to Guardian, it's got fast attacks, and great mobility (skill 2 teleport/blind) and works well in conjunction with Blind Exposure (3 stacks of vulnerability on blind). Sword 3 lets you do a bit of damage at range before teleporting back into the fight.
Torch is great fun, can't beat running around breathing fire on stuff and setting yourself on fire
I tend to run a 0/20/30/20/0 build for Sword/Torch.
Something like this
Stabby Stabby Burny Blindy Build
It's a high crit AH sword build that is based around keeping enemies on fire and blinded, while giving good support to the team.
Start off by using sword skill 2 to teleport to target causing blind and 3 stacks of vuln, sword auto attack has a good chance of landing crits which give you and your team stacks of might, as soon as blind wears off your target hit it with Virtue of Justice for a 5s burn, blind, and 3 more stacks of vuln. Dodge roll out to heal yourself and close by team mates, hit skill 3 to do a short reflect and deal some ranged damage, teleport back into the fight to give the enemy blind and 3 more stacks of vuln. Use torch skill 4 to keep the enemy burning between skill and virtue rotations, and skill 5 to purge conditions from the team (when needed when shouts are on cooldown).
That's just how I play it anyway. We have 2 other Guardian players on our team, so I tried to make mine as different to their play style as possible (within reason, i'm still running AH and some shouts). One uses Greatsword for the pull skill, retaliation and leap. The other plays a ranged pure support guardian running Scepter/Shield + Staff with high healing power dropping lots of party boons and boosting might stacks.
What a killer. 
so still skint
