Idea for a burst build
It’s a bit easier to discuss if you put it into a build editor first.
The ability to stay in DS in wvw largely depends on how you play, if you are roaming then you will be focused and DS is your only real defense. I bet this build would be fun in small group play though.
Also I don’t know that I would consider DS a burst ability, on my engi I can use a burst combo that easaly does 25k in <5 sec. Dagger/Wells would probably be more burst if done right and it will leave your DS open to soak up damage.
This delema is the reason I play MM lol I feel like it’s the best of bolth worlds and I dislike the terrormancer build (it’s great don’t get me wrong, I just don’t like it)
I run those traits with a zerker heavy, Valkyrie light build. It’s very fun in group and Zerg play, but the build I use needs some tweaks for roaming. Still works really though.
