Guild Wars 2

hi, i just found this tooltip a bit confusing :

“You have increased vitality. Healing effectiveness to other allies is increased based on a percentage of your vitality.”

so yea, i get flat bonus vitality (300 IIRC at lvl 80)
but does the bonus in healing only concern the heal i perform on allie ?
meaning that when an allie receive an heal from me, the trait will trigger and add 5% (if i have 500vit)

or will it work on all my “self heal” ?
(ex: Signet of Courage, healing skill, virtue of resolve and any trait that heal me … )

i know the question may look dum, but with Signet of Courage
who said
heal allie ARROUND you ,so i thought “hmm … does that mean i m not included?”
but thankully it also work as self heal.

so yea i find the tooltip really confusing as i never know if a heal will include you or not because it always only mention allie.
so:
shouldn they change the tootip to be more clear ? somethign like: heal you and allies around you[..] but i digress

Nope. Like all “% outgoing healing” effects, Force of Will’s healing boost only affects other allies.

oh, ok, too bad,
well i guess it would be too op.
i can already solo pretty much many boss up to lvl 30 with my lvl 33 guardian
i ll have to find other thing to max the healing
