The Difference Between Woltk and Woltk (Old)

Hello,

I have some questions, what's the difference between the Woltk and the Woltk (old) from the download page?
If I download the Woltk (old) can I play with my friend who played in Woltk ?

If I read correctly, the difference is just the 3d model. Is that right?

Thanks.

it is just about having better looking texture.

Wotlk (old) = Standard client
Wotlk = Client wiht WoD/Legion models ( it has higher chance to crash and some other issue)

I recommend to download Wotlk (old)

ah I see, okay then, thankyou very much :D
