Build help

Looking for a build I can use in open world/story/event's & extremely casual WvW zerg surfing. This is what I've come up with so far, the gear is stuff I already have, and it seems to have worked out ok so far, but is there anything i might change up to make it more effective? I'm not sure how much that little bump in healing power is actually helping in a pinch, but it does seem much more survivable compared to the full berserker/marauder build I was doing. Having a lot less trouble with fights like the Caudecus fight now.

PS i swap out the sword for rifle in WvW usually.

I'd change some minor things:

Last utility slot is optional. You can swap between rocket boots and Hard Light Arena or some other skill.Raspery Cream Food is also optional to keep you rich. Because it is very cheap, increases boon duration about 5% and increases magic find.

In WvW you can either stick with sword and shield or switch to rifle, depending on your personal preference. I'd say both are even.Steamlined Kits is only for beeing lazy: you can achive perma swiftness with Photon Forge skill #2. But it takes more effort. So swap it for Lock On at least in WvW.Also Sigil of Frenzy is not useful in WvW, but awesome in PvE. If you can affort, use another weaopn with other sigil in WvW.
