Good wvw zerg builds?
WvW zerg-builds are based on survivability and groupsupport, which isn’t needed nearly as much in PvE, as result Zerging-builds will have very limited effect in PvE, where-as the other way around you’ll be lacking survivability considerably. Consider getting 2 sets of gear and relearn your traits if you truly wish to be useful in both game-modes.
WvW-builds will generally look something like this:

Empty utility can be anything you like: Wall of Reflection, Signet of Judgement, Save Yourselves for example.
Food I’d recommend either Omnomberry Compote (survivability) Bowl of Lemongrass Poultry Soup (survivability vs conditions) or anything that buffs your damage/Magic Find.
Where-as for PvE it’d be more something like:

As you can see the WvW-build is quite ‘selfish’ when it comes down to survivability, which would be heavily overkill for PvE whilst you’d be lacking damage and thus drag your team down. Not to mention it has little effect to try and outheal PvE-damage since you might aswell have dodged that 1 or 2 abilities a boss uses that would harm you. On top of that in PvE you will be facing different fights with different needs all the time, which makes a full shout-based build a bad idea since you’ll want to be able to swap your utilities around as much as possible. The Virtue of Justice applying Blind/Vulnerability and recharging when a foe dies is invaluable for trash aswell.
If you really insist on finding a mid-way I suppose you could attempt a mixture of Knight and Cavalier gear, it will hurt your damage in PvE and cripple your Survivability in WvW, but you’ll only have to spend 3.5s to respec when you go from WvW to PvE.
