Survivability as Zerk
Save everything for exotics until you tested yourself in full rares.
Wear rares for 2 weeks and then decide which stats fits you better before you get any exotic
full zerk what do you do to stay alive? Is it just a matter of simply dodging appropriately? Is there a particular heal that is better than others, utilities that help you stay alive?
…aaaaand is it viable in WvW, or does that require a different spec?
Staying alive in PvE is a matter of knowing what bosses you’re up against and dodging. I like Stamina Signets passive, +50% dodge regen. Use a Greatsword for damage. Some bosses you cant melee, use Rifle. Against trash mobs, Greatsword hundredblade them into oblivion before they can down you.
Staying alive in WvW is a matter of distance and mobility. Zerker Rifle Sniper Warriors, or Longbow AOE Siege Warriors work well. Melee not so much. Most important here is situational awareness, you need to be able to feel the flow of battle (retreat, advances, standoffs, etc). Use your superior mobility to always stay where you need to, at the fringes of enemy zergs and near your allies, right around the 1200 range mark. Anything fast enough to catch your SW/WH with a headsart probably isnt gusty enough to be on the front lines chasing you.
Sword/Warhorn for large battles where being caught means getting insta death zerg steamrolled, and Sword/Shield for small skirmishes.
In both WvW and PvE, your OhShi- button is Endure Pain, 4 second invul. Balanced stance is a different kind of OhShi- button, to break stuns, stability against CC, and swiftness for mobility.
For healing, probably healing surge, it’s the best “burst” heal. You’re too glass for healing signet to be much use, and against condi builds it’s kill or be killed in the first 7 seconds, so mending’s not helpful esp. if you’ve also got stamina signet.
