Say what you want about WC3:R, the character models look rad as hell. I’m especially fond of this guy:

So as the title suggests, I think warlocks should be able to use shield. Because it would look cool. Plus there’s not much demand on caster shields. Just ele shams and holy pals, and only sometimes. It would be cool to have another player in that game.
Don’t see why not
This would look mighty cool.
Yeah a nice green fel shield 
Do warlocks really need more armor or passive damage reduction?
You’re overthinking it. Balancing is a separate issue. What’s important is they look cool.
only if mages get dule staff like a battle mage
I hear Blizz is letting us use shields along with all the new abilities Warlocks are getting in ShadowLands… oh wait, we aren’t getting any new abilities… hAHAHAHA 
Ok cool, so I guess it’s decided then. I’ll let blizzard know, and we can probably expect this change to be in the game real soon. Good job, team.
Even better, dual-wielded shields.
Please have them remove Fervor of Battle from Arms warriors as well.
I don’t even care if it’s replaced.
As long as it’s optional then totally.
My counter point to this article…
Warlocks should have TWO shields!
I have a prismatic shield that does just as good a job protecting me.
Plus, it makes me look like a really cool Christmas ornament
