Can anyone not vuln stack well?
Guardian for me. I use sword/focus though. I dunno about symbols from traits how well those help
Any Ele can put up a decent amount of Vulnerablity

Necromancer does gnarly Vuln stacking
Before the update to traits I could stack Vuln as a Guardian with Sword/Focus. Not 25 stacks worth, but a decent chunk without a great deal of effort. It seems to me that every profession has the ability to maintain at least a decent chunk of Vuln.
Depends on what you mean by “well”. There’s three things to look at:
#1: How long
#2: What intensity
#3: How consistent
I’d argue that half of the classes fulfill those 3 criteria: Engineer, Warrior, Ranger, Necromancer. The other ones… not as much.
Thief: On their condi builds they get Skale Venom and Deadly Trapper for bursts of vuln, but on power builds they don’t get much vulnerability at all. There’s a paltry amount from sundering strikes, and the weapon skills are too short duration to be meaningful.
Elementalist: Ele’s get a massive burst with Glyph of Storms in air attunement. Otherwise they have miniscule amounts from Weak Spot, and some from water attacks, but water attacks are rarely used.
Mesmer: Gets minor amounts of sustain from the domination line, but often requires interrupts/dazes/shatters to inflict small amounts. Fairly consistent, especially with the sword auto attack.
Guardian: Can get consistent amounts from Symbolic Exposure and Blinding Jeopardy, but won’t be getting high intensity anytime soon.
Seems with the latest fixes posted in the Dragonhunter BWE changes thread, Dragonhunter’s will be gaining the ability to deliver Vuln when they cripple and one trait in particular will make Justice’s passive cripple . . . soo we could see a good deal more Vuln potential from Guardian in the coming days.
