Guild Wars 2

Would the D/P combo that gives you stealth also give you the +2 initiative with infusion? Also, I don’t really understand 2 things. First, how is perma stealth possible with the two seconds long revealed timer and second, why would the combo field be better for stealth than X/D #5?

Thanks a lot for your quick responses!

I guess the topic title puts the question rather clearly. Does Battle Presence count towards Altruistic Healing in any way, shape or form?
