Guild Wars 2

i was doing sPvP today and couldn’t get my PvP gear to work with my actual build and when i was playing i was just destroying people as apposed to my WvW build which cant seem to kill anyone the PvP was just all power where as my WvW build is crit and presision with some power so would a this actually work?

p.s. im still a noob at ele

i just made an elementalist and im not sure how to play WvW with one exactly im not sure which would give me more dps and more of an ability to help my group out while still maintaining decent survivbility.
