Hi Masih! I get majority of my WoW ported models from a mod called Warcraft: Rebirth, you can find it on Moddb. I also got a ton more models from an old, now defunct forum called Warcraft Underground. You can contact YourArthas here on HIVE, he runs a Discord of the same name and they upload a lot of ported models there. You need to be "invited" though, so get permission from YourArthas. Unfortunately, a lot of models were lost when they shut down the original forums, so the stuff on Discord is mostly models from Battle for Azeroth and Shadowlands, with some stuff from WoD.
