With the new patch, the ranger healing skill “Healing Spring” is now a trap.
However, when running “Superior Runes of the Trapper”, “Healing Spring” does not receive the additional stealth and speed bonuses as do the other trap skills. The runes read:
(4): When you use a trap skill, you gain 3 seconds of super speed.
(6): Gain 3 seconds of stealth when using a trap skill.
This may be something ANET overlooked, or maybe it should just be specified only offensive trap skills receive the boons.
