Guild Wars 2

My goal is to be able to run into an enemy WvW zerg and stay in it for as long as possible and then get out alive.

Traits:
30/0/30/10/0

Marksmanship 30: iii / iv / xi
Skirmishing 0:
Wilderness Survival 30: iv / x / xii
Nature Magic 10: iii
Beast Masterty 0:

Utility Skills:

Healing Springs
Signet of Renewal
Signet of Stone
Protect Me
Rampage As One

Gear:

All Power Toughness Vitality

How I play the build:

Pop rampage as one > swoop in > dodge roll > pop protect me when health starts ticking > dodge roll > spam all evades ect > heal > swap weapons/pet > blast heals > spam all evades > signet of stone > signet of renewal > gtfo

Or something like the above

I’m looking for some opinions and input on how to change the build to give more survivability.
Perhaphs mix gear or a different trait setup as an example.
If there are any other builds that accomplish what I am asking that’d be great also.

Any constructive comments appreciated.

Thnx!

Use the Black Bear instead of the Brown Bear, for the AoE weakness. Take Malicious Training to increase pet condition durations, and Shared Anguish for an extra stun breaker. Bowl of Lemongrass Poultry Soup will make your condition removal even better, and Master Maintenance Oil will give you some much needed critical chance. Finally, Sigil of Hydromancy should make it harder for melee opponents to reach you.

By the way, you can’t use two defensive rings of the same type.

Actually I got an ascended ring with a 1 time changeable stats. It let me use 2 offensive rings of the same type so I’m guessing there might be a defensive alternative.
