So what's your favorite utility skill thus far?

I'm lazy, so I usually run in PvE what I might take in WvW.

Blink - which I swap for Portal as needed.
Veil.
Null Field - supported by Glamour Mastery and Dazzling Glamours. Also lets other people combo up with it to add Confusion to their attacks. Not the mention the condition removal on allies and boon ripping (with blind) on enemies. Nom.

I keep Signet of Domination up on both bars, but I kind of like the idea of Null Field + Confusing Enchantments... Dang, may have to rework my build. Again.

I tend to get up close and personal in general PvE so I've found signets of inspiration and midnight come in handy. Since I have some points into chaos, I get a nice boost overall to boons with midnight and the blind can be useful in a pinch. The third slot changes more often but most of the time I use feedback.
