Thief:
Blinding Tuft: It gives you 3s of stealth and blinds nearby foes. It's very good.
Drink: You take no direct damage for 3s after using this spell. It would be crazy if it did not have that long cast time Still very good!
Necromancer:
Skull Fear: A 3s AoE fear with a short cast time. Arguably the best item you can steal.
Throw Gunk: This item shines when you immobilize someone in the Gunk. If you manage to do it, it's one of the best items you can steal.
Warrior:
Shoot Rifle: This is an awesome steal if you are fighting a warrior 1v1 on a point and need to take him off the point to neutralize it. You just have to knockback him with the Rifle and to immobilize him outside with Devourer Venom.
Whirling Axe: It's the highest AoE damage item you can steal and it's easy to land. Very good!
Engineer:
Rusty Scrap Strike: 10s of Bleeding and Poison with 13s of Weakness (remember Lotus Poison) makes it a very good item. However it's a lot harder to land than some other, because it's a melee item.
Throw Gear: 2s stun 900 range This spell is a 2s stun with 900 range. Sounds crazy, right? Well, it has a long cast time and a long travel time, it's easy to dodge/interrupt. Not as sexy as it sounds, but still good. Try to use it as a follow-up to another stun or on an immobilized target.
Mesmer:
Consume Ectoplasm: Well, that one is easy. All the boons in the game for 10s on a 1s cast time. One of your best steals.
Torch Strike: 10s burn + damage Does decent damage and applies a 10s burn which makes it an extremely good damage steal if you run an hybrid build. Like all the melee stolen items, it's hard to land compared to the others.
Elementalist:
Ice Shard Stab: A melee range 10s Chill. Hard to land, but very strong.
Use Scepter: Time to wear a hat and unleash the Harry Potter that you've been trying to hide for all these years. Magical steal, which means random steal. You have a 50% chance to do a 2s melee range single target stun and 50% chance to do a 10s AoE burn around you. Both are extremely good if your build is hybrid.
Guardian:
Use Staff: Harry Potter is never over! 50% chance to apply a ranged 1s stun that bounces between 3 targets. 50% chance to throw a fireball that will deal a good amount of damage and inflict a 5s burn to a single target. One of your best steals in a team fight, if you are lucky that is.
Mace Head Crack: Back to the melee stuff. This one is a melee range 4s daze. It's one of your best steals if you manage to land it.
Ranger:
Healing Seed: Time to unleash the... GARDENER in you! Always dreamed to plant a tree? Guild Wars 2 will allow you to do it! The Tree is a Combo Field: Water, pulses 5 times, gives Regeneration and removes 2 conditions with every pulse. Oh did I tell you that it worked for all your nearby allies? It has a cast time that roots you while using it, but it's still one of the very best items you can get.
Throw Vine: Makes you throw a vine (for real!!) that immobilizes your target for 5s. It is easy to dodge if you throw it from far away, so try to throw it to a target that is close to you. A 5s immobilize is insanely good to take down the target your team is focusing during a team fight.
