WoW characters new model

Greetings,

I deleted accidentally my WoW game 3.3.5a, and I wanted to reinstall(download) the game, but there is no more WoW WoTLK 3.3.5a new. I downloaded the single option on the site, but the game that I downloaded it is the `old one`. I tried to download some updates like Legion character models or something like that, I tried many other options but the game is not the same like before, I mean the texture, the interface, the characters , the gameplay, graphics. I tried to get some informations from the forum or facebook groups , but everybody said the samething, to download legion update...
Could you please help me with this problem?
Thank you very much . :)

They removed problematic WoD models client. What you can do is download the "old" client, and download patches to update the game's looks. It's far more stable, and I haven't had a single crash with updated client with these patches.
