Lady Vashj, the sexy Naga Sea Witch, lost her custom model in favor of a generic elite Naga model.
Here are the differences:
Old Model:
New Model:
While the new model is technically superior in quality, it doesn’t fit the Character’s characteristics.
I agree with the DH lover
I am NOT! 
Oh wow I never knew she had a custom model.
Neat!
Wait… I never realized that the new model’s hair was tentacles instead of snakes. Bring back the snakes! D:
New model has a bigger bra.
My male instinct tells me this is an upgrade.
Does anyone really need six arms? Four seems like plenty, multi-tasking pro. 
Her dagger got brighter
Bigger bra just means more covered skin.
I vote for older model too. Medusa hair is cooler and coloring is prettier on it too.
The cleavage isn’t that Impressive on the original model.
Atleast a bigger bra invites my imagination to go wild.
Wait. Is she coming back or is her model just getting updated?
Her model got updated in 7.0.
I’m just asking for them to bring the old model back.
you are a few years late to this party aren’t you?
new models nice, she still drops loot which is what we all really care about 
That’s definitely not what I care about.
What I really care about is how long I have to wait for Tainted Elemental spawns to kill her.
I don’t think the model update is robbing her of identity, as much as it is correcting errors in the past. No other naga model has six arms. Lady Vashj was the only one. That tells me the naga weren’t fully thought out ahead of time. Not even Queen Azshara has six arms.
Ya it’s like an avg sized dude buying the xxxl magnum condoms. (There’s a lot of extra material there).
Lies, I saw you hugging a DH last night when you thought you two were alone!
Dead demon hunters don’t count. Mortis loves dead DHs.
