Need a hand with build/gear for WvW

If you wanted it more defensive just switch the listed jewellry to something with toughness/vit, and if that’s still not defensive enough for you, replace the listed runes with either divinity for a balanced approach, or something else that’s super defensive I guess.
The build survival mainly comes from well-timed use of cooldowns though, and if you get jumped by more people than you can handle there’s no reason you shouldn’t be able to outrun them unless it’s a huge zerg, or they keep chain immobilizing you or something.
Potaters!
