It cannot be a central part of the build because it’s 1/s ticking aoe skill so it has to suck on bosses.
But of course it can play an important role in clearing trash.
I like some Pierce WoP - Infiltrator with it. Check the crossbow in the builds below
Ulvar’s beginner / SSF build: https://www.grimtools.com/calc/Q2zjKER2
- but you can see WoP is not the main damage source as there are also
- Chillspikes
- Blade Spirits
Crucible optimized build: https://www.grimtools.com/calc/bVAaaYlV
- not many points in WoP though
Also something with Goredrinker, i.e. this by afanasenkov26

2 x Chillheart to convert WoP to Cold
Chaos WoP with something added to it, there’s a lot of possible builds
Elemental WoP + Obliteration Deceiver by Plasmo:

You could make some Vitality WoP using Decree of Malmouth, i.e.
[1.1.4.2 - 1.1.9.0] Vitality Deceiver. 150-170 5m 30s. SR 80. Crate of Entertainment. Callagadra. Avatar and other bosses
Physical, Aether are also doable
