Guild Wars 2: Top Nine Skill Combos

To bring some more attention to the combo system in Guild Wars 2, IGN managed to convince the developers at ArenaNet to slap together a list of their favorite nine skill combos. Some interesting ideas in here, and I suspect some will be far more powerful (overpowered?) than others:
Healing Spring + Unload = Bullets that Heal
Profession: Ranger, Thief
"The skill Unload is one of the best ways to put out a ton of damaging projectiles, but when you combine it with a ranger's Healing Spring, you get a completely different effect. A ranger creates a Water Field with his Healing Spring skill, which a thief can then Unload through. These healing projectiles grants an area-of-effect heal to any allies that are attacking the thief's target. This healing doesn't apply to bad guys. This combo is one of the best ways to add some healing to an ally who is deep in hand to hand combat."
-Matt Pennebaker, Game Designer

Super Elixir + Illusionary Duelist = Condition Eraser
Professions: Engineer, Mesmer
"We call this getting Bearced! An engineer with Elixir Gun fires a ground targeted Super Elixir creating a Light Field. Then a mesmer with a pistol can summon an Illusionary Duelist to fire projectiles through the field, which will remove conditions from allies near the target."
-Tyler Bearce, QA Tester
