Guild Wars 2

Yep, it seems that it doesn’t work
Here’s a video just to show it: https://youtu.be/M48dFNvuccU
Note that the Berserker’s Power trait didn’t activate when I used the longbow F1, but it did when I used the greatsword F1

Using the burst skill for the longbow (Combustive Shot) along with the Berserker’s Power trait doesn’t give the trait’s intended buff even if the attack lands.

Edit: In the video I used the greatsword burst skill (Arcing Slice) which did trigger the trait, but the longbow burst skill did not trigger the trait.
