D/P stealth wombo comboooooo
It does work, but smoke screen is much more obvious, which causes problems to a thief trying to escape…on the other hand it blocks missiles, and you can ground target it, so you could use it as a distraction if people are aoeing your smoke screen.
I think it just comes down to – you have 3 utilities, and while this is a nice trick, it makes much more sense to take blinding powder for emergencies, and shadow-refuge for the long stealth. That leaves you with one utility left, and going without a stun-breaker is asking for trouble…so shadow-step or shadow-trap, and now you’re out of utilities.
After messing around with it in WvW I changed from D/P+SB to D/D+S/D. I can drop smoke screen and heartseek through it like 7 times. Tons of stealth. I dropped shadow refuge from my utility bar and going smoke screen, shadow step, and blinding powder… all deception skills. With trait Master of Deception, all these utilities have reduced cooldown %20. You have longer periods of stealth, with the need to spam heartseekers half the time. Pretty cool.
