You can pretty much take whatever weapon you want to any build. But, I can give you some example what I use what weapons for.
Starting with Main-Hand Weapons.
Sword; it’s a strong damage weapon, with a blind and a reflect ability. I usually use sword for strong damage and AoE damage, since it hits foes around it as well, and to support my allies, by blinding the enemies and reflecting projectiles. The sword is also very good for roaming (as in, running around, since you can target any enemy and teleport forward.)
Mace; this weapon I sometimes use in a dungeon if the enemies take a lot of damage on my allies, I don’t really need to say more. The symbol applies regeneration, your auto-attacks heals yourself and your allies with the third chain, you also get a parry attack.
Scepter; ranged weapon, nothing more, nothing less, good for fights where you can keep your targets away from yourself or allies by using the immobilize skill.
Let’s continue with Off-Hand Weapons.
Shield; my favourite, and this is what I use with the sword, you got skill that does damage and applies protection to yourself and allies, and also a very good knock back skill to interrupt anything.
Focus; a weapon that protects yourself from damage, and also gives you a ability to cure condition, apply blind and heal. The focus is pretty much a weapon that mainly ’’focus’’ on yourself, and not the allies around you. It’s good to have if you need to shield yourself for some seconds from heavy hitting attacks.
Torch; a damage off-hand weapon, it works great in dungeons with the burning, the burning condition is really strong. It’s a good AoE off-hand.
Going for Two-Hand.
Greatsword; everyones favourite it seems. It’s the strongest damage weapon in the game for almost every profession I would say. For Guardians it’s a great support weapon too because of the symbol it places, giving people retaliation, deflecting damage back to the attackers. Overall it’s just a weapon that does great damage, and a little bit of control because of the chains, great for interrupting or pack enemies together to AoE down.
Hammer; a great control two-hander. It controls your enemies with symbols, and wards and heavy AoE blast damage. It works good pretty much everywhere, mostly in modes where you meet other players and battle against them, since many bosses or similar can just run through everything since they got permanent stability. Otherwise a really good AoE weapon with support abilites, since it applies protection.
Staff; a great support weapon, and a great AoE weapon. The staff got some healing abilites which works great anywhere. The might stacking is also really, really good. The AoE auto-attack makes it awesome in zergs in WvW or enemy packs in dungeons.
That’s pretty much it..
