Healing to Allies v Outgoing Healing
I’m imagining you’re thinking about the Ventari legend right now. Anyways, the answer is no. When it says to allies it means to other allies, not you. I’m not sure about what it means when it just says outgoing healing. I suppose your healing skill is technically coming from you so I’d think so, but who can tell.
Petition for Anet to clarify this.
They both mean the same thing, and that extra healing effectiveness doesn’t effect you only your allies.
This is so that when other players heal you, you don’t get the extra healing power because they didn’t have that ability. Its a form of balance/redundancy (I guess it works)
And the way healing works, unless its a static heal (like blasting water-fields) the heal scales to the player that its applied too. So when I grant Regen on a player that has no healing power investment, the amount they Regen is lower than the amount I Regen for, these traits/abilities make up for the lack of healing power so your support/healing character is more effective in combat if you have these traits/abilities. For water-fields, the static heal is scaled to the player who casts the field, not the player who finishes it with a blast-finisher.
